Profile NoBoss cranks are exactly the same as our Race Cranks, with the sole exception that they lack a boss to bolt a sprocket onto them. They require you to run a Spline Drive Sprocket or Spider. They can be used for left or right hand drive.

Crankset includes crank arms, 19mm GDH heat-treated CrMo axle, GDH crank bolts, flush washers, and crank installation/removal tool. Titanium upgrades available for axle, axle bolts, and sprocket bolt.

Guide for 19mm axle lenghts:
-6.0"(for 68mm & 73mm external Euro BB's)
-6.875"(for 83mm & 100mm Euro BB's)
