Wolf Tooth Front Through Axle - FOX 15 x 100mm Black Wolftooth axle uses a captive steel washer under the head to reduce friction on the fork leg. This protects your expensive forks and converts tightening torque to the cramping load to create a rigid welding surface that prevents the axle from sticking or baking. It is also a great alternative to lost or damaged factory axles. When installing, apply a small amount of grease to the washer and the screw part. 7075 T6 aluminum designed and manufactured in Minneapolis MN USA.
