Mission Prodigy Trials. Posted December 27, 2009 Report Share Posted December 27, 2009 Hey, What is the difference between a M14 and a M15 crank bolt because on Tartybikes they have Echo Sl crankbolts in M15 size only and I am wondering if they would fit my ZHI Isis bottom bracket.

Mikee Posted December 27, 2009 Report Share Posted December 27, 2009 (edited) I believe ISIS bottom brackets are either M12 or M15. Not M14 or M15. I think your ZHI bottom bracket is M12, But i'm not certain. Best thing to do is measure the width of the threaded part of you current crank bolts, and if it is 12mm the echo sl bolts won't fit, but if it is 15mm then they will.

Mark W Posted December 27, 2009 Report Share Posted December 27, 2009 I'm running an M14 BB - however, it's a super light ti jobber so that's why.Just saw a photo of an ISIS BB that's apparently from Zhi, looks like an M12... Quote Link to comment Share on other sites More sharing options...

Thank you everybody. Quote Link to comment Share on other sites More sharing options...
