Very high-grade, durable chain guide (factory edition) from US market leader T.M. Designworks with replaceable inner part. The chain guide consists of a CNC machined PTFE block, which avoids bending of the whole chain guide. In case of shock, the chain guide returns to starting position. Indispensible for Enduro and Cross Country, but also used in Motocross. T.M. Designworks chain guides are used by many professional and factory teams around the world.
