Race Face CRANKARMS SIXC CINCH CARBON

Completely hollow carbon crank arms.

Industry standard 30mm spindle with Cinch spline interface.

The spindle is CNC machined from a commercialized aluminum 'super alloy' that is 20% stronger than 7050 alloy (the alloy commonly used in this application).

Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments.

The interchangeable spindle option of the Cinch system allows you to use the same crankset with 68/73mm and 83mm frames, as well as the RF BMX spindle and spider.
