Question 4x84 or 4x90 better for distance crosstraining?

Hello! I'm a female ultramarathon runner who's switching from Blue Streak Avenger quads to inline skates for outdoor training (adore my Blue Streaks but sick to megadeath of avoiding / hitting / flying over stupid stones), and so need advice please. My situation:
  • Skate sessions will be 20-40kms 1-2/week, mostly solid longbase to complement more specific run workouts.
  • Prefer safety & control over excess speed & ease of speed - am there to workout after all, and cannot afford a crash injury!
  • Currently an intermediate to advanced level quad skater, will spend rink time retraining stops etc. for inlines.
  • Will skate on sealed roads and footpaths, just the usual bumps, cracks, driveways, and stones.
  • Am light-framed, 52kg human if it makes a difference.

I've done a bunch of research and feel either 4x84 or 4x90 setup would be best for me. I really like the sound of Adapt Hyperskate Zeros, and of course they look great for casual use as well as for training, but am also considering Seba models such as GTX84, GT90, Trix 2 90 (hard to tell which is best for me!)

Any thoughts would be appreciated!

Stupid stones? Well, I have same problem, but the difference is that I'm already on 90x4 inlines. Still fall. Yes, longer wheelbase give stability, but don't expect that switching to inlines will fix the problem entirely.

Sit as low as possible. Don't try to double-push. Use longer setup 90x4 (100x4 will go too) and a full set of protection. Since stones as antipersonnel mines are always ready

Naw man! I thought they must just pop out of the way of curved inline wheels, rather than act like doorstoppers on the flat faces of quad wheels!

I'll definitely still be wearing protection for my training, but how do so many inline skaters get away without wearing protection if it's still easy to fall? I rarely see pics of inline skaters wearing more than wrist guards.

Anyway I'm pretty sure now that I'll go for Seba Trix 2 90 skates.. should I seriously consider 100s now instead? 4x100 is such a long wheel base that I cannot imagine feeling very nimble in anything other than a straight line.

Haven't tried quads but inlines must perform (on stones) better. But you'll loose the grip for a moment anyway.
I stumble on stones 10-15 times in a season, this one was lucky one with zero falls, previous one with 2 falls.

Maybe they skate where there are no stones? Dirt, sand and puddles in a park are easier to cope with. Stones is an attribute of motor roads (at least here where I am) and everything that is unlucky to happen too close to them.

Well, 10.8" 90x4 was enough for me to start having problems with crossovers. They weren't nimble for me at first. And they are still too short for high speed cruising in my opinion. So, if you have to spend some time learning crossovers anyway, it doesn't matter 90x4 or 100x4 you choose (hope I managed to explain the logic). Longer frame give more roll and stability, but are harder to accelerate and turn.

Speaking about your case, I don't really know. If you have long straight runaways, I'd lean towards longer variant from two given.
100s may feel too heavy, but I saw several ladies on 100x4 and 100-90-100-100 attached to slalom boot (RB Maxxum, Sebas etc) and they looked statisfied. Must try on to know for sure how it feels.

Trix have 165 mounting, you can buy them with shorter frames and will have an opportunity to try a longer frame in future. And switch back if it feels bad. Used speed skating frames don't cost much, here in Russia you can get 100x4 with wheels for a price below 100 USD. In "a land down under" things must be cheap too

PS be careful choosing those slalom boots, they are often harsh and have few room in a toe box.
PSS long frames have two main variants of spacing: 165 and 195 mm (some other like 150, 160, 180 are present but rare), and (again rarely) 2nd wheel rub problem.

Inlines can have problems with a straight crack/sidewalk line if the entire frame drops in it.


I can't recall ever having much of an issue with rocks on quads or inlines unless I was going really slow, with my feet side by side instead of correctly staggered, or possibly had hit a tiny pebble indoors with hard wheels on. Any skateboarder would know what that's like. Instantly getting your wheel chocked by a pebble SUCKS.

Been outdoor skating for a long time, so I'm used to it I suppose.

Inlines are a lot better for sidewalk cracks and the like, that is for sure though.

Oh, on the wheel size. Most find the bigger the wheel the better the ride if you can handle the height and length.

Many if not most will "pop" out of the way, at least much better then quads. Trail snakes (root bumps) small sticks and such are still trouble. And as Mort said watch out for cracks in the direction of travel.
Now about those sticks etc. Always keep some knee bend and skate with your weight a bit more on the rear wheels. even more when you see them coming. It will let you roll over them. Think of a boat, if you put all the weight in front it will try to dive down, if you have more weight in back it will try to ride up and over.
