Title: I need some super cheap crank arms
Post by: POTOOOOOOOO on March 27, 2026, 09:26:50 AM

Hey all.

I need some cheap crank arms for my turbo trainer bike.

They need to be a 3 bolt SRAM chainring fitting with ideally a 30mm axle, but 29mm will also work.

Any suggestions please

That sounds like a Senicx PR2 job: https://aliexpress.com/item/1005006082575629.html

I think the other cheap 3-bolt options for road bikes (Prowheel, Goldix) only come in 24mm.

Or the ZRACE, witch i think is the same as the Senicx https://it.aliexpress.com/item/1005010692898957.html (https://s.click.aliexpress.com/e/_c4UpjV4h)

Thanks guys.

That ztto could work but I wouldn’t mind something shorter than 170mm.
That’s my current length, so wouldn’t mind taking this opportunity to experiment.


Any more than 50-60 euro and I might as well get a used SRAM force crank.

If anyone has any other suggestions, I’m open to any ideas.

The PR2 exists as a 165mm variant, but can be hard to find - does this work for you?

Thanks.

I decided to go ahead and buy some SRAM Force arms for a very good deal.
