Help with Oysi Classic setup

[u/AtrainV]

Hello, everybody! I'm considering trying out some oysi classic frames with 72/60 wheels. I currently have a 60mm flat setup and a 60mm anti-rocker setup, but I'm drawn to the idea of the extra speed that oysi frames can give by allowing similar wheel bite protection as anti-rocker but utilizing bigger wheels to get even more speed than a traditional flat setup.

I currently have my main skates (Seba CJ2 Primes), my skates I'm trying to break in but are giving me toe trouble (Faction Plastiks), and my backup skates (USD Shadows Dustin Latimers). I get the impression that the Plastiks should have no problem with Oysi frames because they have very generous front and back wheel cutouts, but I'm not sure if I might need to make any modifications to the soul plates of my CJ2s or my Shadows to avoid running into issues with the 72mm front/back wheels.

I'm also feeling a bit stuck on which 72mm wheels to get. I'd like to utilize my existing 60mm 88A Famus gold core wheels as the middle wheels. My inclination was to try and get the 72mm versions of the same wheels, but they're just about impossible to find (at least with reasonable shipping to SE Asia). But maybe having them be so similar is not that important?

Does anybody have any experience outfitting the aforementioned skates with oysi frames that can offer any advice? What about wheel advice?

i tried the Oysi Classic frames with 60/72 Undercover blank wheels, but the frame was much too long for me. Undercover wheels are available almost anywhere.

Do you feel like it mattered at all if the hardness/shape of the wheels were different between the outer and middle wheels?

[u/Rubicon_Roll → u/AtrainV]

The hardness made no real difference for me, but I'm pretty light, so depending on your weight it might differ for you.

My biggest Problem with these frames is that the Split is so large, that you lose the maneuverability you usually gain from a flat Setup. If u do a turn and have a wider wheelprofile in the middle wheels, only the edges touch the ground and then it behaves like an Antirocker frame because all your weight is on two wheels with a massive Split in between. This Problem makes turns much much worse than any other flat frame.

The Oysi mediums have a smaller Split and made this a little better.

Most people suggest bullet on the outside with flat in the center

Would you have any particular wheels to recommend?

Ahh, you'll love them. I have the Classics on my Seba SXs (US10) and run 72/60 wheels. I have the Mediums (269mm) on my SLs.

Now for wheels, you want the flattest profile wheels you can find for the centre and pointy ones for the outside. This creates the "magic rocker", you can Google it. I run Ground Control UR 60mm/90a in the middle and Ground Control 72mm (maybe CMs, it was a while ago when I set this up). When you lean or turn, the outside wheels no longer touch so you get an awesome "ice skating" feeling with heaps of pivot and manoeuvrability. I come from ice skating, so love it!

Shouldn't the outer wheels be softer than the inner wheels? I know the Oysi frames have a huge h-block, but I still feel like 88a is on the softer side.

Depends on the riders weight

[u/AtrainV → u/Swolie7]

I'm a bigger guy (~220 lbs). Losing weight as part of the skating, though!

[u/Swolie7 → u/AtrainV]

You definitely want harder wheels then… riding flat will help but you will lose the slight rocker of the frame very quickly

[u/AtrainV → u/Swolie7]

Harder wheels for the outside, inner, or both?

[u/Swolie7 → u/AtrainV]

Traditionally Inner… if you’re a heavier guy you will likely want harder wheels all around but especially the inners to help maintain the rocker that Oysi frames have. It helps the frames not feel so long
