What Is a Through Axle on a Mountain Bike and Why Is It Important?
A through axle is a type of wheel attachment system commonly used on mountain bikes that provides added stiffness and strength compared to traditional quick release skewers. It involves a hollow axle shaft that slides through the hub and is secured on both ends with threaded nuts or levers. The through axle system facilitates better alignment between the wheel and the frame, enhancing handling and stability on rough terrain.
