Fit Key Guard Sprocket

The Fit Key Guard Sprocket is the one piece guard version of the Key sprocket, CNC machined in the USA from 7075 aluminium with 1/8 inch teeth. It uses Fit's tooth profile for better chain engagement and longer tooth life, and was created with input from Ben Lewis.

The integrated guard protects your chain during crooks and slides nicely when you are in a crank arm grind, and it can be run inside or out. The centre bore is 15/16in (24mm) with 19mm and 22mm steel hat washers included, there are four rotation positions, and there is plenty of guard clearance for popular half link chains.
