Woodcraft axle sliders are designed for racers with a focus on ease of use and practicality. Woodcraft axle sliders help to protect the valuable fork lowers and swingarm on your bike in the case of a crash. Woodcraft has worked long and hard on these axle sliders design to ensure they ONLY ADD 5 SECONDS TO A WHEEL CHANGE! No more dealing with through rods, simply pull the quick release pin and you're ready for a wheel change. These pucks have received the perpendicular mounting design passed down from Woodcraft's patented frame sliders to provide a solid sliding surface, maximizing puck life.
