The T.M. Designworks chain guide comes straight from motorsport and offers the following properties: CNC-machined from Teflon. With replaceable chain running surface, hence extremely durable. Specially designed for the challenges of off-road use. Note: Pay attention to clearance when used in combination with a 2K chain guide. The chain guide may need to be adapted accordingly.
