XR Classic Freeride Bumpers are individually handmade through fully compression molded UHMWPE plastic. What does that mean? Well, it means they're darn near indestructible which is what you need if you're riding rough terrain or hitting the streets. They also slide like butter if you're trying to get tricky with it. Bumpers are wear parts and are designed to take a beating but the Freeride Bumper construction is built to far outlast the stock Bumpers which means you won't need to swap them out as often saving you money and plastic in the long run.
