The Topeak DeFender XC1 & XC11 Set delivers full front and rear protection for 29” mountain bikes, shielding you from mud, water, and trail debris. The XC1 front fender attaches directly to fork lowers using a secure QR bolt system, while the XC11 rear fender mounts with an adjustable slip joint clamp for a custom fit. Made from high-impact plastic with a polished underside, both fenders minimize dirt buildup and ensure lasting durability for rough terrain and wet weather rides.
