A complete OEM drivetrain refresh for when your chain is stretched, skipping, or your sprocket teeth are worn. This set pairs an RK 420 chain with a 12-tooth front sprocket and a 30-tooth rear sprocket, so the chain and both sprockets wear in together instead of a new chain running on old teeth.

Compatible with: E-Ride Pro SS 2.0, SS 3.0 and SR.
