I thought I'd start a post collecting weights of different brand and model quad plates. To make it an apples-to-apples comparison I'd like to collect weights of plates of the same wheelbase together.

This is the weight of the plates with cushions, trucks, and axle nuts included, but WITHOUT wheels or toe stops.

I'll start things off by posting weights of my size 160 Roll-Line Driver and Mistral/Navigator plates. If anyone else posts weights I'll add them to this post.


Roll-Line Driver, size 160: 526 g (18.6 oz)
Roll-Line Mistral, size 160: 495 g (17.5 oz)
Roll-Line Mistral 160, drilled to lighten it: 445 g (15.7 oz)
Roll-Line Variant, size 160: 485 g (17.1 oz)
16 Atlas Figure E97: 550 g (19.4 oz)
6 Ultimate II: 388 g (13.7 oz)
154 Boen: 306 g (10.8 oz)
156mm Powerdyne Reactor: 397 g (14 oz)
Kiwimaster's Carbon Plates with boen trucks/kingpins, length 165: 275 g (9.7 oz)
Sure Grip Super white magnums, length 155: 400 g
Sure Grip Super white magnums with toe stops cut off, length 155: 340 g


Plates with lengths other than 160

Labeda Proline 725 (184mm): 408 g (14.4 oz)
Sure Grip Super White Magnums Size 5 (173 mm) 17oz/482g


Interesting that the extra $100 for Navigators instead of Drivers buys you a 1 oz weight savings.

Roll-Line Driver, size 160: 511 g (18 oz)
Roll-Line Mistral (same as Navigator), size 160: 480 g (16.9 oz)

The Navigators also have left and right toe stops. The Driver does not. The Driver and Variant are the same plate, (plate only, not king pins here) just different coatings. The Navigator shape requires more machining as do the toe stops. This is where the cost increase comes in.

Thanks. I agree totally. It's obvious comparing the Driver and Navigator side by side that the Navigator plates are more complicated to manufacture, so I was in no way meaning to imply that Roll-Line is trying to rip anyone off. It's just that, since I just use jam plugs, the only relevant difference for me is the weight.

So why did we put a Gator on your sk8s?? We could have done Giotto... It is even lighter....

What's a Gator?

I got Drivers on the skates I got from you. I considered going to a Giotto, but have found that I actually like tapping my toe plugs a lot when jam skating, so I think I'll stay away from NTS plates.

I'm going to replace the Drivers with the Navigators I just bought, which will be straightforward since they're same size. Then I'm planning to mount the Drivers on my other pair of 811s, which currently have size 9 Reactors. I keep one pair of skates setup for outdoor and one for indoor, but I've found that I like my Roll-Line shod skates so much better that I end up just switching between indoor and outdoor wheels on them rather than use the Reactors, so I decided I need Roll-Lines on both sets of skates. It'll be my first attempt at mounting plates, but since it's exactly the same boots and plate size as the set you put together for me, I can just copy the mount location from your set.

bilboa, how exactly did you weigh your plates - like were they complete with the axle nuts? Toe stop/plug in or out, etc?

Here's a few of my own that are in that same size range (all were weighed complete with all parts and the axle nuts on them and no stops or plugs):

160 Variant - 17.1 oz
160 Driver - 18.8 oz
160 Mistral with a bunch of metal drilled out of it - 15.7
16 Atlas Figure E97 - 19.4 oz
6 Ultimate II - 13.7 oz
154 Boen - 10.8 oz :eek:
156mm Powerdyne Reactor - 14oz

I have found (and bilboa's info confirms it a bit more) that Roll Line plates vary quite a bit from plate to plate even when you have the exact same model and same size. I have not been able to find any differences that I can see when this happens, which only leads me to beleive that there are some differences in the actual metal being used. I know the different models use different metals - but that doesn't explain the difference between the exact same size and model.

I weighed the plate with cushions and trucks installed, but WITHOUT wheels, axle nuts, or toe stops/plugs. Since your measurements are with axle nuts, I can weigh mine again with axle nuts too. Or I could just weigh my axle nuts and subtract that from your numbers. Thanks for the info. I'll add it to my list.

My Carbon plates with boen trucks/kingpins weighs 275g,size 165.
Thats 9.7oz.
These are the plates we made back in 1991,we can go lighter now if we make the boot from carbon as the plate does not have to resist as much twisting,the boot can do that now.

Time to find a good postage scale (or someone that uses) to get the weight of my NTS Pro-line. This actually is a good reason to pull them off, it's only 4 screws anyways.

Hi Kiwimaster,
in your last post you have the blue writing section and you mention Brian Davis ex Bont Boot maker.
I use to work with Brian at bont and then for many years after I would train and race with Brian on the Ice.
Yeap Brian makes an excellent boot but I didn't think he was making them anymore and quads well that is news to my happy ears if he is.
Or are you referring to Bonts Carbon boots and those being stiff?
Do tell..... quick quick the waiting is making my bearings spin out of control. :D

Look forward to hearing more soon,
Scott Corey.

Hi Scott,
Brian made my inline boots about 5 years ago. I don't think he is making boots anymore,last I heard from him he was building a recumbent bicycle.

Your the guy making wheels right? I need someone to share my new skate concept with..it needs a wheel!

Thinking out loud here... but couldn't carbon plates also be mounted on something like the carbon quad racer using an epoxy based glue? Total elimination of mounting bolts so even more weight savings?

I am very disappointed to see how heavy the Navigator plates are. I was planning on purchasing a set soon.

I saw in another thread that the Roll Line Ring plates had what appear to be 45 degree angle trucks similar to the XK-4's that I currently skate on. If so, I would be interested in knowing the relative weight of the Ring plate.

The weight of the Roll-lines is something you only notice when you have in your hand. When you are skating they work soooo damn well you will never notice the extra few ounces. I can go from my NTS proline to a Navigator and the weight difference is hard to tell.

I second the motion for having the trucks able to slide forward & rearward, but this is going to give some kind of weight penalty, UNLESS ....

Are you suggesting the plate be eliminated and the boot can receive the "truck modules" by mounting directly into a channel/slot/groove integrated into the carbon fiber of the sole? Sounds great, especially if the truck positions could be independently located. Then we could really do some fine tuning!!

The weight of the eliminated plate would cancel the gain of the added channel/slot/groove too.

For me the weight difference of my Prolines doesnt outweight the overall performance of my Drivers.... Yeah the Prolines are noticably lighter to me but for the way i skate... nothing can beat a Roll Line!

Renegadeine, I weighed my size 6 XK4's (7 3/16") and got the exact same weight as your size 4's. Is this possible? Are yours cut in a different shape perhaps? (mine were weighed with nuts on)

Mine:
Sure Grip XK-4 Size 6 (182mm) 21.4oz/606g

Just a side note: I weighed all the wheels I have [without bearings] (Fanjets, some unknown with aluminum hubs, and radar speed rays) and they all were about the same weight. I then weighed my new Atom Strokers (without the lip) and the Strokers where an even ounce lighter per wheel. Changing to the strokers lightened the load by 4 ounces per skate. That I believe is significant.

Because manufacturers want to make big profits and they won't do that from a niche market.

And BTW those Boen Speeds are brand new old stock, just waiting for the perfect boot. Sometimes having small feet can be a good thing.

The pair I weighed are older ones (maybe 70's vintage), with new trucks and with axle nuts, using a digital kitchen scale. The jump bars don't have holes in them like the newer ones I've seen. It is possible that the differences between older and newer versions are the reason that your size 6 weighs the same as my size 4.

This is an interesting observation. I have Sure Grip Super White Magnum plates in both size 5 and 6. I stripped them today to prepare them for polishing/plating. I now have the white trucks.

Weight of plate stripped bare, nothing but the plate itself, no hardware, no rubber, no trucks, no toe stop, no toe stop screw.

Size 5 (173 mm) Left: 184g Right: 199g
Size 6 (184 mm) Left: 199g Right: 184g

Weight of magnesium plate, magnesium trucks, titanium hardware, nuts, axles, red cushions) no toe stops are:

Size 5 (173 mm) Left: 384g Right: 398g
Size 6 (184 mm) Left: 398g Right: 384g

So, the size 5 and size 6 plates weigh the same (total), but the left and right plate weights differ by 15 grams for both sizes, and the weights are 'swapped' from left to right between sizes.

The reason why the longer plates weigh the same as their shorter counterparts is that the longer ones are narrower through the middle.

I am impressed Blown, only 4 days ago you were running yellow trucks and didn't know the difference. Found out, decided to get them and presto 100g on each foot in only 4 days. You should try running one skate with the yellow trucks and one with the the white and report how noticable 100g is in the real world.

I thought I'd start a post collecting weights of different brand and model quad plates. To make it an apples-to-apples comparison I'd like to collect weights of plates of the same wheelbase together.

This is the weight of the plates with cushions, trucks, and axle nuts included, but WITHOUT wheels or toe stops.

I'll start things off by posting weights of my size 160 Roll-Line Driver and Mistral/Navigator plates. If anyone else posts weights I'll add them to this post.


Roll-Line Driver, size 160: 526 g (18.6 oz)
Roll-Line Mistral, size 160: 495 g (17.5 oz)
Roll-Line Mistral 160, drilled to lighten it: 445 g (15.7 oz)
Roll-Line Variant, size 160: 485 g (17.1 oz)
16 Atlas Figure E97: 550 g (19.4 oz)
6 Ultimate II: 388 g (13.7 oz)
154 Boen: 306 g (10.8 oz)
156mm Powerdyne Reactor: 397 g (14 oz)
Kiwimaster's Carbon Plates with boen trucks/kingpins, length 165: 275 g (9.7 oz)
Sure Grip Super white magnums, length 155: 400 g
Sure Grip Super white magnums with toe stops cut off, length 155: 340 g


Plates with lengths other than 160

Labeda Proline 725 (184mm): 408 g (14.4 oz)

I skated a set of sub 1 kilo skates last night (Boen's, Bonts and Deanos, very similar to Aussie Scotts photo but with old school Bonts and red deanos) and it is amayzing how nice it is to have skates this light. I swapped wheels on the right foot to Fan Jets and the increase in weight was quite noticable compared to the feathers on the left...........the search is now on for some lighter wheels.

Working on weight reduction for two sets of Laser Sliders with 190mm axle spacing bar (too heavy & carbon fiber upgrade will drop 30grams on this large bar).

The NTS model is currently at 340 grams with slide bar still steel (56 grams) and Kingpins still 2" long chrome plated flat hex socket head bolts (26 grams) .
Glue mount eliminates all mounting bolts & nuts (38 grams)

After kingpin upgrade to 7075 aluminum at 2.5" & 2.25" (front/rear), and most of steel bar converted to carbon fiber (except ends remaining steel) --
Expected weight ====> 285 grams (9.5 oz.)!!

Not bad for a 190mm axle-to-axle plate. PICs coming soon.

Thanks Johannes,
I wanted to use a better lighter shoe than one in PIC- but the new 225 gram Nike Raketa badminton shoe with Flywire technology is not released yet.
This would have put me into the 900-1000 grams zone. Not bad for a large/long 190mm plate build!

I have only used GOOP brand urethane adhesive on all my glue builds.
They have all been glass filled nylon or plain nylon. I sand surface well to prep. On my 1st build, I used no plastic primer, and it still held fine. Recently, I have used 3M plastic primer (meant for plastic assembly using their double stick tapes) which seems give a slight improvement in adhesion. I am testing a new 3M spray primer/glue now, which is rated for polyethylene and propylene (both super difficult to glue), but so far it seems too gummy and not a good match for the urethane. No matter what glue you use --MOST IMPORTANT THAT YOU TEST TEST TEST! Appply a test blob and let dry fully, then pull it off and confirm it does not release easily.

Note that the urethane shrinks some as it dries. So, minimizing the gap in the bond zone is important. Choosing a flat soled shoe/boot also critical. or follow up glue will be needed ro refill the larger gaps after 1st glue shrinks. Sole must be thoroughly cleaned of any mold release residue. I sand soles too, both to make flatter and to present fresh rubber to the glue zone.

Good clamping is critical. I have a 2" wide 1/4" thick wood piece that fits inside shoe (remove insole). Then I lay some wheels inside shoe on wood. Top jaw of clamps press on wheels-to-wood-to-sole. I also use 3-4 velcro cinch straps in addition to the 2-3 clamps.

I try to lay down glue not to close to edge, but with enough build up so that clamping just squeezes it out to the edge. If too much comes out, let it dry some before scraping away. Do a final thin bead at edge after 1st glue dries & smooth with wet finger.

With the current project I went for carbon fiber sole stiffener for weight, appearance, and to have 100% close contact with the Slider's nylon, since it has so little area to bond with (especially at the heel zone). Note the good contact in the PIC. I may still have to screw on piece of carbon plate at heel to widen plate some there, since this narrow of a contact is pushing the limit for the glue there. I will also likely glue the slide to main part of the plate, since it is not designed for tension loading (without screw mount, no compression happening and rear hanger could pull of the slide).

Remember to TEST YOUR GLUE. Yes it takes time, but it could save your life.

I've been contemplating this recently with my bont carbons: Is the carbon stiff enough to just get rid of the whole middle of the plate and mount the hangers directly to the boot?

I would make oval shaped carbon fiber plates a little bigger than the hangers and then urethane glue them to the hangers to spread the load. Then screw & glue the hanger/plate combo onto the Bont (adding some glue for more strength - It CAN be peeled off boot later). This makes a lot of holes though. If you want to use ONLY glue to attach to the Bont, you need to have minimum gaps in the contact zone (for urethane glue).

If the bottom of your Bonts are NOT rather flat over the hanger/carbon adapter contact area, then you will need to use Epoxy to bond the flat carbon fiber pieces attached to the hangers onto the Bonts. Epoxy should bond well to the Bont's Acrylic resin, and epoxy also fills gaps well (better than urethane), plus it sets up much faster. Then the only place you need the urethane is between hanger nylon and the bottom of the carbon fiber adapter plates.

Remember to ALWAYS TEST your glue's bonding strength to every surface involved, before doing final assembly!

As I glue the Laser Sliders to the Carbon fiber laminate, I am using SHOE GOO and finding it to dry faster and harder than the other generic versions of GOOP line of urethane adhesive products.
I got this BLACK SHOE GOO at a skateboard/shoe store, where it is popular for repair of worn skateboard shoes.

Good Idea, because there are too many different Urethane-Glues out there to test it all.
Maybe Shoe-GOO is availible here also. But I wait for your longtime-expierience ;)

More than stiff enough but I have yet to see a sole that is true enough to align the king pins in the vertical axis front and rear....

With a NON-FLAT shoe/boot bottom, aligning the kingpins vertically is no problem, unless you are stuck in the NO GLUE zone. The glue can fill any gaps resulting from the normal contours of a Bont carbon fiber sole. You might need a jig to align the truck hangers while the glue dries though.

Alternatively, you can just glue a thin sheet of carbon fiber laminate onto the sole to create a DEAD FLAT mount surface. After glue sets, cut away the excess laminate in the middle arch area to leave behind two oval shaped flat and perfectly aligned carbon laminate mounting zones for gluing on the two hanger assemblies.

Of course, if you ONLY want to be SCREWED on, then just try using a bunch of washers to get your kingpins aligned. Have fun that!

My latest outdoor GLUE build 1190 grams; Size 10 shoe. Soon to be dropping another 100+ grams with titanium axles, 7075-T6 (or 2024) aluminum kingpins, and aluminum slide bar replacements. This shoe at 385 grams (13.5 oz), is also 190 grams heavier than my ideal shoe (Nike Flywire design) - and this means another 200gram (6-7 oz.) further weight reduction is possible, which makes an UNDER 2 LB. skate (908 grams) well within range. Not bad on a budget of just over $200!

Bingo... The jig is the issue. I'm not 100% sure the glue as filler is a good idea either??? Perhaps an epoxy product in this case?? Although I yank your chain about the glue, Don't think I am not giving is serious consideration in some applications... :smile:

Alternatively, you can just glue a thin sheet of carbon fiber laminate onto the sole to create a DEAD FLAT mount surface. After glue sets, cut away the excess laminate in the middle arch area to leave behind two oval shaped flat and perfectly aligned carbon laminate mounting zones for gluing on the two hanger assemblies.

Another interesting idea. But if we are putting Snyder hangers down they probably have less than 1 sq inch of contact area each. That would be less than I would be comfortable with...Especially in a indoor derby situation....

Of course, if you ONLY want to be SCREWED on, then just try using a bunch of washers to get your kingpins aligned. Have fun that!

You are probably right on the epoxy for leveling up the Bont bottom, unless you want a little more cushion from the urethane. Bigger gaps favor the epoxy, plus it sets up way faster.

Is it just me, or is there not a clear pattern that those most willing to muck up threads this way by totally going off topic are often also those with typically very little real interest in the actual topic (no prior relevant posts), or those whose views are know to be antagonistic to the on-topic ideas being presented in the thread.

I also request that SLF posters respect the integrity of the thread topics and and the general direction of discussion material within them, and when people ignore this reasonable guideline, then they deserve the tactful kind of reminder that SSpinball just posted here.

1. Do you still use alloy kingpins?
Yes, Grade 2 Titanium 3/8-16 on Laser Slider - no problems.
Yes, 2024 aluminum 3/8-16 INDOORS ONLY and under my heels only. Limited number of hours before replacing them too - not advised for general use (too weak).

2. Did the alloy kingpins you boasted about in this thread work without breaking?
Some did and some didn't. After a couple hundred outdoor miles I couldn't trust them anymore. I was the only guinea pig in this experiment, and it WAS discussed in the thread as an experiment

3. Do you realise that once you put these ideas out here some noobs might copy you and cause themselves an injury?
Yeah I do realize this, but we all have a right to do our own experiments. One guy even wanted to do aluminum axles too -- I did my best to discourage him on that one.

There you go I can count to three. Can you please give 3 yes or no answers?

Now that you proved you can count to three, I DON'T have MORE FAILURES than you can count. Most serious inventors will typically count far more failures than successes. In the end they finally hit the target though.

They only broke skating OUTDOORS though, but YES I did break three, and worst injury was a slightly torn ribcage muscle that felt like a sword was being run through me every time I sneezed.
I have skated them at indoor speed class and even doing NTS "duck run" starts without a problem, but they can't really be trusted, and when they fail they give ZERO WARNING.

Would I recommend them for others? NO. Even for indoor only use? NO.

However, I will likely be doing another round of tests soon using stronger 3/8-32 and M10-1.25 aluminum kingpins

I don't get it. You say you can't trust them, but persist. Strange fellow you are.

It is the level of stress they get exposed to that determines whether or not the aluminum kingpins fail. As you well know, outdoor skating delivers probably 3 times higher levels of peak dynamic loading stress to kingpins. It is possible that these aluminum kingpins would last a very long time in light duty indoor rink skating. However, I cant be certain of how long it might take before they could still eventually fail, even indoors.

Knowing that the three outdoor failures were always with the front kingpins, and were also an instant drop-you-to-the-ground scenario, I decided that I never wanted to have another one of those happen to me, but with a heel kingpin failure, it is much easier to avoid a face plant kind of a fall, or even possibly ride it out.

So for a while I continued to leave the heel kingpins with aluminum and front with steel. Finally I just did them all in Grade 2 Titanium.
No more worries.

Now that I have access to a lathe, I can properly fabricate them so that they will be less prone to this kind of failure.

Hey okie,

The Laser plate at 351 grams is pretty decent considering all that steel hardware.
You could likely go under 300 grams with titanium kingpins and axles. aluminum jam nuts, and nylon washers on the cushions.

Skins looks good, but I cant stand the SA trucks with the NO-BALL-TIP pivot pins. Those urethane cups and tapered tip pivot pins just don't have what it takes to get a smooth full range action. Plus the kingpin hole combo stud-or-bolt design with lame 3/8-20 thread & hex pocket is weak. Did you put a nut in the hex pockets and use a fully threaded bolt in order to squeeze the plastic between the jam nut and the top nut? It's the only way to make that hole design have a solid kingpin mount.

Yeah I was surprised how chunky they are, for the way they are designed there seems to be a lot more meat than they need.

So I took them apart, a lot of the weight is in the kingpins. They are solid steel as are all the retainers, they weigh a ton.
Might have to look into some alternatives.

To combat the view of shiney and heavy Okie promotes, I weighed my new Royals from Doc:

7" Royal SS NTS with ti jump bar = 449 grams or 15.83 oz
7" Royal SS NTS with ti jump bar and 7075 aluminum wheel nuts = 461grams or 16.26 oz

For comparison, my genearlly considered pretty light plate of same (almost) wheelbase
180mm Reactor = 420 grams or 14.82 oz
180mm Reactor with stock black Reactor thin wheel nuts = 447 grams. or 15.77

Okies 7.5" Art proline without wheelnuts and before it went the way of the old man in the mountain in New Hamshire = 439.8 grams or 15.51 oz

So that is a difference of 1oz per plate for the Reactor vs Royal, and only .5oz per plate when you factor in the 7075 wheels nuts.

For the royal vs Proline it is only a difference of .3 oz. I think even Okie could manage to lug around these shiney heavy plates, and these are not munchkin sized either :wink:

Hey Finn,

Can you post a breakdown of the component weights on that skate:
Trucks alone?
Plate alone?
Kingpins alone?
Other misc stuff alone?

Finn 427
June 1st, 2012, 09:31 AM
OK. Here is a breakdown for you with a variation. I am sure after i go over them with my usual cleanup they will be less again:tongue:

Trucks are Boen Specials = 61g
Kingpins are Racing version = 19g for the 2
The plate on its own = 83g
Cushions = 22g
Here is a variant. The pic in the OP has a pair of Ally retainers for the barrels and Stainless retainers for the cones, plus an ally jam nut.
They weigh 15g but with 4 ally retainers 12g

Total of 258 on what I weighed which is a bit different to the OP but the parts are not identical as you can expect. Here is a pic of the Kingpins. I can add the rest if you really want them;)

Finn, thanks for the breakdown.
The kingpins are really lightweight. Not sure how they can do the job and still be so light.
The revised total sounds more accurate.
I was thinking that with 120+ grams for the truck pair, there was no way to get all the other stuff to be totaling up at only just over 100 grams more.

My all nylon Laser Slider bare plate of similar wheelbase weighs in at just 82 grams, but that is without the jump bar. Adding another 13 grams for that and it goes up to 95 grams. So I am still finding it surprising that your all all alloy bare plate tips the scale at just 83 grams. That plate must be a lot smaller than it looks.

Here are all the pics you need.
If you add in a set of Wes custom trucks, the weight is less again. This is a small plate, but if someone has a longer Racing pase plate, Please weigh it as it wont be much different i would think as the Specials are only a few grams different between sizes.

Finn, so with the new PICs I total things up just over 250 grams [CORRECTION => 258 GRAMS]

Where I place the lower limit for how light a small wheelbase factory setup metal plate can go is about 250 grams, but a normal avg. mens size wheelbase will be more like 270-275 grams.

Then TI flips can still drop another 20-25 grams perhaps from your gram total, and this would really give an amazingly low weight for an all metal plate @ ~250g.

Has anyone got a weight on the re-released Rogua plate? I'd be curious to know what they tip the scales at.

On another note, I've seen some drilled out outdoor NTS plates. Has anyone drilled out excess material on a labeda NTS? With a carbon bont I would think it would work. Any ideas on potential weight savings? I didn't notice a weight for a labeda NTS proline. Anyone have a weight for one? Maybe I missed it.

In all cast products your are going to get a weight variance. I Build hipo outboard boat motors. The connecting rods are casted. They vary in weight from the lightest 331 grams to the heaviest of 371 grams. Usually a matched set of rods from the factory are within about 5 grams. These are in 20,000 powerheads. I machine them lighter, and weight match them perfect. Anyway just saying 5 sets of plates of the same kind will prolly all weigh a little different.
Even a set of 6 forged pistons cnc'd machined exact and lightened from the factory are a few grams different. Each weighs around 400g. A set of 6 pistons are over 2,000, and within 3 grams. Spending 300.00 or less on a complete set of plates I don't think they worry about the weight being exact for every set. JMO

I just had a new set of avenger mags delivered today. No toe stop, but with the toe stop screw, and axle nuts. size 5. Right is 496g. Left 494g. 2 grams with all that hardware is purdy good. IMO

Yes, it takes the full Ti package to even get those to be anywhere near close to a pound.

Yet despite all the Ti upgrades , they will always remain high strength blingy boat anchors - great for landing triple spin jump tricks if you can get them elevated high enough off the floor in the first place.

I'll go as light as possible, but wont sacrifice axle strength to save weight. 7mm threaded bends soooo easy.

Still waiting to see what the side project brings as weight goes . Honestly I could probably change to aluminum axis pins in the new setup :) might be able to squeeze it down to 300 grams . Hey Richard if it gets that low, get yourself one

One option these are missing, is the world dominator cross bar.
This is a doc/DVW special, but essentially you get a ti cross bar off a synder world dominator 3 sizes smaller than the size of the royal (in this case a size 10 would be needed) and bend the ends to fit the royal hangers, and you save yourself another 30+grams roughly. Those steel cross bars are hefty. My size 11 royals, with ti jump bar and aluminum wheels nuts is 449 grams

Ti bars are overkill. 7075 aluminum would be plenty strong enough, and save enough more weight, depending on size, to get below 1 LB for most all sizes.
Plus, the 7075 polishes up brighter than Ti does.

The synder ti jump bars are already made, have the douglas snynder stamp so look more "OEM", they just need some carefully bending in order to fit a royal. This ti also polishes very well on a buffing wheel and has the benefit of never tarnishing unlike aluminum

You could not use flat bar 7075, the bend to match the hangers would be to severe, so in order to do it right you would need to mill them from 1 inch barstock which seem over kill to me.

Gotta be careful bending aluminum and stressing the metal at the bends. I was making a aluminum set with 6061 and was going to polish them up but upon inspection under a magnifying glass there were small cracks on the ends so I scrapped the idea.

Mort if you are wanting a strong 7mm axle try the Sure Grip Magnum axles. Everything I get from Doc I request these axles for their strength and durability. I believe they are the toughest 7mm axle out there at the moment.

8mm bearings, so easy to come by, and where quads arent supported on both sides like inlines are, ill take the strongest largest axles I can get. Kinda want 10mm Ti and use a 6900 bearing. :D. Would need a custom made one from ole Wes tho, thicker truck where the axles go by at least 2mm to accommodate the increase in axles size.

I thought 8mm axles were usually poor fitting and bend easier than the typical higher end 7mm axles. I am sure you, Sidewinder, or JSDarling can machine up some sweet axles, but how do standard Riedell 8mm axles compare to a Roll Line or Proline 7mm?

The Arius axles are supposed to be made from chrome moly steel, not sure if all riedell axles are or not.


We need some bend testing done :)
But theres this
http://ncalculators.com/area-volume/circle-calculator.htm
So we can easily input values, get a surface area and use that for a rough guess on strengths.

7mm axles

3.5mm radius

Circle circumference 22
Circle area 38
Diameter 7


8mm axles

4mm radius

Circle circumference 25.1429
Circle area 50.2857
Diameter 8


The circle area is almost 33% larger in an 8mm axle than a 7mm

10mm axles

5mm radius

Circle circumference 31.4286
Circle area 78.5714
Diameter 10

Thats about 57% more area than an 8mm axle, and more than 200% of the surface area in a 7mm axle.

7mm axle = 38 square mm to 0.0589001 square inch
8mm axle = 50 square mm to 0.0775002 square inch
10mm axle =78 square mm to 0.1209 square inch

Im out of time for lunch so if someone else wants to do some calculations on mild steel, hardened steel and titanium based off that square inches.. :) but you see that a 7mm axle would have to be no less than 33 % stronger in materials alone to equal the strength of an 8mm axle.

You are right that the 30 bending of an aluminum 7075 jump bar would likely initiate cracking. Looking at the side view, it is clearly too much of a bend. 15 or maybe 20 can work if done carefully, but 30 is better suited to Ti material.

Let me apologize ahead of time for being a picky Mechanical Engineer.

These numbers mentioned are good for shear and tensile calculations, but experience shows that axle failure occurs from bending. This means Section Modulus is the guiding number. I'll jump ahead and say the real comparison is the ratio of cubed radius. So for 8mm and 7mm: 4^3 / 3.5^3 = 1.49. Or, the 8mm is 49% stronger than the 7mm in a bending situation.

6-4 TI has a yield of 128 ksi. 4130 steel has a yield of 75-85ksi. So I am confused why Ti would yield before steel. (I'm referring to an old Doc post I read today) The manufacturer could use a different grade or heat treatment for the Ti. They might have a reason, like to allow bending instead of fracture, but without tensile/chemistry testing it's anyone's guess.

I hate it when people try and reinvent the wheel.
Why are you worried about strength of an axel if you skate an arius.
Plenty of other things to break first......

Let me apologize ahead of time for being a picky Mechanical Engineer.

These numbers mentioned are good for shear and tensile calculations, but experience shows that axle failure occurs from bending. This means Section Modulus is the guiding number. I'll jump ahead and say the real comparison is the ratio of cubed radius. So for 8mm and 7mm: 4^3 / 3.5^3 = 1.49. Or, the 8mm is 49% stronger than the 7mm in a bending situation.

Good quality 7mm steel axles will more normally be made from a material closer to specs of alloy socket head cap screws, which are typically 170KSI tensile strength

The best Grade 5+ alloys of titanium fasteners come in at ~150KSI tensile

No apologies needed sir, Im in over my head there aside from numbers available vs real world results. I know they are not the same though. It was just a example of available material for more resistance to bending or deflection as axle size increases. All axles will deflect some, but the better things are made, tighter tolerances and closer slip fits, the stronger the assembly becomes.


Theres also fatigue with stressing metals, not sure how much it matters in skate applications for axles, but we do see broken Aluminium kingpins from prolines from even the lighter skaters (115 lbs) fortunately @ EWNB one year we had spares :) I convinced a skater friend if one broke the he should get them all replaced just in case.

Ahh. That makes more sense. If I remember correctly; most ASTM A574 (socket head cap screw material) is made from heat treated 4142 steel. So It could be considered chrome molly. And now that I think about it you would want the steel harder than a standard quenched and tempered 4130 or 4140 - To prevent bending.

The whole idea of using Titanium hardware is weight reduction. It will never be a s strong as the 4340 heat treated axles, but it weighs far less. When you start to add up 4 King Pins, 4 axles (flips no nuts), TI pivot pins you start to shed incredible numbers when your ultimate goal is to get the weight as low as possible.

There has always been complaints of Grade 2 Titanium bending. it is not even as close, not in the same ball park as 6al4van. This is a fact look at the tensile Strength numbers, or the Modulus Elasticity numbers for the two, (Areospace Specification Metals, web site) it breaks it down very well.

What I know for sure, I have had countless Axle's, Pivot Pins, and Kingpins made from 6al4van shipped around the world now since I started machining for anyone that wants them, and have not had to remake a one. All different weight's of skaters, different types of skating, Speed, Jam, Derby, no complaints (Knock on Wood).

2 Mysteries:

1. I actually ordered the RK Speed SL (the ones which aren't trenched through: http://www.boen.it/scheda.asp?idprod=448&idpadrerif=110), and realized they sell the Ti kingpins separately and the SL doesn't come with them. So I sent Boen a note and said "Can you just swap the steel kingpins for the Ti ones in the SL i ordered, and charge me the difference?" - he said sure. I figured i would get an SL with Ti king pins, but what turned up is the trenched through version, in the size i ordered (size 17/180mm). It must be the RK Speed UL (lighter version), but that size isn't available on their website.

2. The page for the RK Speed UL (and i guess the other speed plates?) does themselves a bit of a disservice: http://www.boen.it/scheda.asp?idprod=446&idpadrerif=110. They list "Frame weight 380 g. (16 size)" yet the frames i got (as you can see) are about 360g, and size 17 (180mm) - a full 12mm longer than the 16 (168mm).

So after all that rambling, here are the photos:

You really need to give a WARNING!!! → Weights shown are TARE ADJUSTED to HIDE THE WEIGHT OF THE BEARINGS!

It would be a neat trick but the weights shown have not been tampered with in any way :wink:

I just noticed that these are NOT 608 22mm bearings, but rather the much lighter 16mm size micro bearings. Still, these wheels with 688 bearings installed are same weight as the RB Turbos without bearings.

8mm axle micro (688) and 7mm axle micro (167). Quite light, very nice wheels :smile:
