Default Weight Weenies - how much does your stuff weigh?

Here is my new new Aluminum Laser Slider Bar upgrade for 190mm plate on Sz. 10 shoe.
Shaved 25 grams from replacing the 56 gram steel bar. It is a right angle triangular aluminum tube with sides drilled & countersunk.
New skate weight 1129 grams.
After steel kingpins replaced with aluminum => 1085 grams
After shoes replaced with Nike 200 gram Flywire shoes = 899 grams per skate.
YES! an under 2 lbs Size 10 long plate outdoor skate is within striking distance, and an under 1000 gram skate with 70mm wheels is now also possible!

I am somewhat amused by the recreational skaters who find an extra gram or two of skate weight so very critical to their "performance". They will explain their equation for how much difference blah blah amount of weight lifted per foot adds up to by the end of a session... whilst carrying an extra 30 pounds on their caboose or around the middle. Apparently I'm missing some crucial skate weenie point

If you don't know what the lightest skates you have ever skated weighed, then you have no business asking the question you asked.

Why? Because you don't know what you don't know.

And until you DO know what you don't know. Asking such questions can only make you look less smart than the Snartin I know you are.

P.S. Don't conflate the two distinct domains => skater and skates.

I know what you meant... I'm not a total moron in understanding the concept. The same point can be made with running shoes which I AM/was more familiar with. However the point remains the same regarding session skaters. I somehow doubt the few extra grams of skate weight can be blamed for taking the boogy out of someone's shuffle when they're smuggling lard under their Tshirt

I fully agree with you if it comes to crossing a finish line first-- weight= time. Which is why you seldom see corpulent distance runners.

For the most part though I was being facetious

Default 2000 grams per skate

My skates weigh 2000 grams each with indoor wheels on. My outdoor wheels might add a little, but not much, considering the Bones Super Elite wheels on them now.

That doesn't slow me from boogying at bit. In fact, for indoor, I use movements of my extended leg to change edge, turn, etc.

Outdoors, I've never had a feeling of wearing cinder blocks on my feet. And maybe the extra mass down there damps out the rough-surface vibration.

To compensate, I HAVE shed 10,000 grams of body fat in the past few months.

Geez, and here I was figuring I was doing good by hitting the bathroom before I skated a session.

For some wierd reason...Ive never liked very lightweight skates... I guess since im used to skating on Roll Lines...i like to know there is something down there. Ive got some Chester Mans mounted to Labeda Prolines that id love to weigh! Those things are by far the lightest skates ive ever skated in. Sad thing is, is that i dont have a scale like the one you've provided Im gonna put my 70mm Velocity Race wheels on them and take them to my mother-in-laws house and weigh them... I seem to recall seeing one of those scales lurking in the "ebay" room

You can get these scales dirt cheap. Mine was $7 plus $6 to ship.

I can see where a big jump in weight dropping would put you off initially.

In titling this thread I acknowledge that some of us get obsessed by skate weight, and the flip side is that some also remain oblivoius to it.

There is no good or bad - that's just how it is.
I am not going to say there is any PROPER amount of attention to be paid to skate weight,

Has anybody tried narrowing the width of big wheels? Not sure how much weight it would save, but would it have an impact on rolling comfort?

I have done it.

Before the wheel was 200g without bearings, after about 156g with bearings.

I suppose, the harder the wheel is, the more you can narrow it. A soft wheel will get more rollingresistance if it is to narrow.

Interesting. I think I'll try it on an old set of wheels. Is there a recommended percentage I can get away with taking off?

It's a combination of things...really.

I am skating the lightest pair of skates I've ever skated. Put together a new setup after I broke a kingpin while skating my 20+ year old setup.

I have new wheels that offer better grip and roll. I also have new boots, bearings and plates. My plates are more than 50% lighter in weight (Sure Grip Classic versus Snyder Advantage). These combinations of things make skating more enjoyable to me. My wheels offer better grip and roll but because my plates are lighter I can skate for a longer period of time without getting as tired. New bearings make the roll seamless (Bones Swiss). The new boots offer more support but a way more comfortable than the old boots I had.

All-in-all my skates are lighter in weight but that alone doesn't make my skating experience any better. It's a combination of things. As we get older we tend to need lighter weighted skates or we wind up doing less skating, especially if we're not in very good physical shape. So the weight of the skate is important.

Default Are you taking off from inside, outside or both?

peter,
Depending on your wheel design, how much you remove can vary.

I don't like to have the wheelbase keep getting narrower as the wheels are narrowed, especially when they are already 70mm or larger size. So if the insides can be cut outward at an angle of 10-20 degrees, this is how I would start the process. I believe Johannes did this on his ABEC11 project.

Default Narrow is not all...

I believe it is a combination of parameters wich make a wheel fast.

Looking to bicycle tyres (bit different, but at least they have to roll also ...)

The reason for the very thin racingtires is wheight and applicable pressure = hardness.
They made comparisions between thick and thin tires, and found out:
With the same pressure the thick tires have less rollingresistance than the thin.
But the thin ones have less rollingresistance if they pumped up to 8 bar while the thick ones could only get 4 bar.

Im not sure that we can adopt this to 100% for quad wheels, but it shows the direction.

Default narrow?

How come indoor "speed" wheels are wide?

Like I wrote, compared with the same hardness wide tires has less resistance then narrow ones, in the bicycle world.
So indoor wheels are hard, so they can be wide bec. they are not restricted by applicable pressure as tires are. And they are used on a smooth surface.
But for sure it is only true in a certain frame. I dont think that a 8cm wide hard wheel is faster than a 4cm wide one with the same hardness.

When it comes to asphalt there are more variables into play. A wider wheel can slow you down as it has a wider contactpoint for the rough surface.
The rougher the surface a (normaly faster) harder wheel slows you more down than a soft one. But if the soft wheel is to narroow, the flexing and deforming is more and the resistance increases.

Conclusion (subjektive and for outdoors): a narrow hard (83a) wheel is not rearly faster in average than a 30 to 35mm wide middle (81a) wheel.
But the 81a wheel is a lot more comfortable and has better grip on bad surface. Your feet like it, and for that you can skate longer.

On smooth asphalt the 83a wheel is a bit faster.

Default Because indoor wheels are HARDER & have to hold on curves

With indoor wheels, holding grip on the turns is key to sustaining speed.
It seems that wider wheels allow for faster cornering.
If you had a mile long indoor straight track, I believe the narrow wheeled skaters would go faster.

Baah, Humbug.

Bont boot, Boen plate, Fafnir Bearings, Cruciani Wheels: 700 grams all up.

Screw messing around with crap - just buy the best, and skate it.

Your Shoe Size? --- at 700 grams, that skate is certainly SMALLER than a US Sz. 10
Axle-to-axle is WAY LESS than 190mm too, and your meager foot cushioning with the Bont sucks as well.

Give us a breakdown of your "700 grams" weight==> Wheels + bearings? Plate+ mount screws? Boot?
TOO MUCH of the "Baah, Humbug" and NOT much useful information.

Your $500+ unobtainable build:

$300+ Bonts are still in production. Boen Plates - NOT in production, rare & used price $Big; Rare Cruciani wheels - $$?

My real world possible build:
$120 for Nike 210 gram Flywire shoes; Laser Sliders 210 gm., NOT in production - Ebay used price $50+; carbon fiber 45 gm. +$30; Pacer Twister 65mm wheels 395 grams $40; replace all steel H/W ~$10; Total $255 => for 900 gram skate
