Wolf Tooth Front Axles are lightweight, easy to use, and friendly with your fork. They are available in a variety of colors and lengths for Standard, Boost, and Fat Bike forks. They use a captive steel washer under the head that protects your fork, transfers more of the tightening torque to clamping load for a stiffer interface, and prevents the axle from sticking or galling when you want to remove it.
