3-bolt Direct Mount Update

Updated mount for 3-bolt DM chainrings allows spacing to match established chainline offsets. This allows you to use other 3-bolt DM chainrings of any brand.

Wave™ Tech
The Wave™ tooth profile alternates from left to right, directing lateral forces into each link to keep the chain active. This design creates more open spaces to dissipate debris and abrasion, maintaining chain retention in adverse conditions.

Note - Bottom bracket
The Girder Gen2 M30 crank requires a Praxis Works M30 bottom bracket as the axle profile of the bottom bracket tapers from 30mm to 28mm. Suitable M30 bottom brackets from Praxis Works allow the use of the crank in almost every frame.

Additional weight: 488g +/- | 170mm set without chainring | manufacturer specification

Scope of delivery: left and right crank arm with axle.
