Great crankset but the spec listed on this site is wrong. This crankset does not feature an interchangeable spindle. You can not change it out for a 30mm CINCH spindle as advertised and RaceFace will confirm this.

Replacement for my Santa Cruz Tallboy. I had the 175, but wanted to shorten the length as I was getting quite a few pedal strikes. This has helped out a ton. Exact replacement. These are bomber tough and excellent quality. Great customer service with Performance Bicycle - I had a return and they processed me quickly. (different order)
