Park's Shop Cone Wrenches are made of durable tool steel and are thin to fit the low-clearance adjusting nuts and cone flats on hubs and other bearing assemblies. Park's special Y-heads put more material where it's needed for excellent durability and holding power. The 26mm size fits through-axle end caps and suspension fork crowns. Most applications require at least 2 cone wrenches. Call or stop by. We can recommend the correct sizes for your needs.
