COMPATIBILITY

BB - Praxis M30 MTN cranks use our M30 family of bottom brackets. This crank can be installed with M30 : BSA, BB90/92, T47 E.B, BB30/PF30.

DM1X CHAINRINGS - With all the different MTN frame types requiring different chain lines, combined with many riders preferring oval shaped rings or colors, we wanted to make things easier for you. So we updated the Girder arms to align with the industry spacing for the common DM ring offsets. This now allows you to run any brand/type/style of 3-bolt DM ring and get the correct chain line. See Pic - On the backside of the G2-MTN Cranks you’ll see a ring guide decal to get your desired chain line.
