ROCKBROS FK-892 Adjustable Off-Road Bicycle Fenders Set for MTB 26-29 inch - Black

Mountain bikers tackling muddy trails know the struggle of mud spraying up from the wheels, soaking clothes and obscuring vision. The ROCKBROS FK-892 fender set solves this with a pair of flexible, quick-release mudguards that mount in seconds without tools. The front fender attaches to the fork arch, while the telescopic rear fender slides onto the seatpost and extends to provide extra coverage when conditions get messy. Both fenders are made from high-impact polypropylene that bends on impact and snaps back, so they survive brush, rocks, and the occasional crash. Adjustable angle and length let you fine-tune protection for 26", 27.5", and 29" wheels, keeping you drier and your bike cleaner on every ride.
