The Profile Racing No Boss Race 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.
These cranks are constructed of 4130 chromoly and feature 48-spline arms and a 5.625" gun-drilled hollow (GDH) 19mm CrMo spindle. Flush washers, sprocket bolt, and a crank installation/removal tool are also included. It requires a 19mm bottom bracket (not included).
