The Acerbis chain guide, replacing the original component, guarantees greater impact resistance thanks to the high-strength plastic material. The guide is made in two pieces: the body and the slide, the latter replaceable once worn, also allowing you not to have to disassemble the chain when replacing the slide or the guide itself. The controlled elasticity structure of the guide absorbs shocks and minimizes damage to the chain and crown.
