Profile Bossless Race Cranks
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 also be used for left or right hand drive.
The crank kit comes with crank arms, a CrMo Gun Drilled Hollow 19mm 48 spline bottom bracket spindle, 6mm CrMo GDH Crank Bolts, and a Profile Crank Install tool.
Please note there may be delays with Profile cranks.
Bottom Brackets are sold separately.
