Riro 24mm axle carbon crankset

[pavlo.k]

Does anyone have experience with Riro carbon crankset with 24mm aluminium axle?

Thinking about getting one on for my new build. The frame has bb86 bb shell and I don't really want to go for a dub crank.
Was looking around for some lighter 24mm axle cranks and could only find this Riro crank and a raceworks one.
Any feedback on how those axles hold up?

I have three of them in use. They all are fine. You will probably have to experiment with BB's. I had a Ali BB in my BSA frame and it was too wide. The Shimano BSA BB's are a little narrower and those do fit.

Hey mate, I have a Riro at the 50/34 chainring. Has around 500km on it so far, so I cant comment on longevity. No issues installing, I do have a T47-79BB.

I'm using 3 Riro/Racework cranksets as well. No issue with the 24mm alloy axle and I use these cranks on two road bikes and a gravel bike. Though the same issues with BB size is a concern. If the BB is too wide, it won't fit properly. I had to switch back to the Shimano BBR60 threaded BB and BBR72 PF BBs to have them fit across my different frames.

how wide is too wide? I'm planning to use a token bb86 thread together bb. It's probably same width as a shimano pressfit bb86 bottom bracket.

Damn, I just took apart the crank on my gravel bike yesterday. Had I seen your post before that I would have measured.
The difference is only about 1mm, but with the wider BB the bearings will seize when tightening the bolt before it is tight enough.

they're fine. the only caveat is that it doesn't come with any indication of the bolt torque, which is not much. I ended up stripping it but I found a way to replace it
