Moustache Bikes Jean - Carter de protection

The Jean Chaincase Guard is an original Moustache Bikes replacement part designed specifically for the J range, covering the J. on, J. all and J. off models across all drivetrain configurations. A properly fitted chaincase does a straightforward job: it acts as a physical barrier between your drivetrain and road debris such as mud, gravel and water. This helps keep the mechanism clean, slows down component wear and means fewer visits to the workshop for cleaning and adjustments. As a genuine OEM part, this chaincase is built to match the exact geometry of Moustache J frames, no trimming, drilling or adaptation required. Whether you're replacing a damaged part or refreshing a used bike, this is the dependable, like-for-like solution.
