Shimano Sm-ax55 12x142mm Thru Axle Quick Release

The extra stiffness of the thru-axle over a standard quick release provides a seat-of-the-pants difference in how the rear end behaves through heavy trail chatter or when standing hard on the pedals. With a cam on the head lets you easily secure that rear wheel in place.
