The Profile Spline Drive Sprocket (Limited Edition Halahan Winter Cloud) is just like any other Profile Spline Drive sprocket, made in the USA from 100% billet aluminum. Set up to be used in 48 spline / 19mm spindles without the need of a drive bolt much like the Tree sprocket. Profile is always doing good stuffs.

The Profile Winter Cloud colorway is the signature color for rider Shane Halahan. A bead blasted finish down to bare metal with a matte clear coat on top give this a unique look.
