The KEY GUARD is the one piece guard version of the KEY sprocket with our new tooth profile for better chain engagement and longer tooth life. Created with input from Ben Lewis to protect your chain during crooks or slide nicely when in a crank arm grind.
Made in USA
CNC'd from 7075 aluminum for strength and style.
15/16” (24mm) center bore (19/22mm steel hat washers included)
Integrated guard for chain protection can be run inside or out
4 rotation positions
Plenty of guard clearance for popular half link chains
