Made from high impact-and rub-resistant honeycomb 380 microns semi-rigid PVC, the All Mountain Style Honeycomb Chain Guard is specially-designed to protect the chain and seat stays of your XC, gravel, cross, or road bike from impacts, scratches, and chain rubbing. It has an exceptional ability to conform to even the most difficult curves of your bike's frame and allows repositioning while installing, making setup essentially foolproof. Plus, it's made from automotive-grade materials so you don't have to worry about deterioration or yellowing over time.
