The RacingTime chain guide, replacing the original component, provides greater impact resistance thanks to its high-strength plastic material. The chain guide is made in two pieces, so that the chain does not have to be dismantled when replacing the patrs. The controlled elasticity structure of the chain guide absorbs shocks and minimises damage to the chain and chainring.

Factory chain guide reinforcement, developed in collaboration with the racing department, protects against stones and bumps. CNC machined from ergal and andodized.
