The I - type axles come with a left - side housing that allows you to adjust the lever position easily.

Using this axle unit is a breeze. First, make sure your bike is a modern disc brake bicycle suitable for a 148x12mm E - thru axle. Insert the axle through the wheel hub and the frame, then adjust the lever position on the left - side housing of the I - type axle as per your preference. For maintenance, regularly clean the axle with a dry cloth to keep it free from dirt and debris. Avoid using harsh chemicals that could damage the materials.
