Hi David - These cranks should work fine with the RockMan ISIS BB. The 165mm length would be closest to your standard cranks. Thanks, Mark

Hi would Bonz freewheels would fit on this?

Hello - The Bonz screw-on freewheels should fit on these cranks fine, with a bashring or with a spacer instead of a bashring. Thanks, Mark

Ben

Hi, what sprocket would be needed to pair with these cranks

Posted by Ben on 22/06/2018

Reply from TartyBikes on 22/06/2018

Hi Ben - You can use either a screw-on freewheel or a screw-on sprocket with these cranks, it depends on your bike setup and requirements. Feel free to send us an e-mail with some more info about your bike and we'll do our best to point you in the right direction! Thanks, Mark

So how do you attach a chainring to these cranks? I can't find a screw on at 22T.

Hi Ryan!
It isn't possible to fit a chainring to these cranks as they are designed for use with a screw-on sprocket or freewheel. Trialtech used to make screw-on sprockets in this size, but haven't done for a few years now.
We do stock White Industries ENO Trials Freewheels in 22t which could be used with these cranks and a Trialtech Sport Full Bashring, but you would then need to take your rear freewheel off and fit a screw-on sprocket instead.
Unfortunately the only other options we have for a 22t setup would be either the Trialtech Race Square Taper Cranks, the Hope Crankset or the SRAM GX Eagle Crankset.
