What is a thru axle on a mountain bike?
What is a thru-axle on a mountain bike? A thru-axle (TA) is a wheel attachment system that secures a wheel on a hub between a pair of dropouts on a bicycle frame or fork. The thru-axle threads directly through the fork/frame holes and into the wheel hub, which makes the wheel secure from detaching.

Measure the straight length of your axle shaft. Do not include the axle head or tapered spacer, if there is one. Axle length is not the same as hub length. A bike with a 12×142 hub standard will have a significantly longer axle since it will have to go through the frame on both sides of the 142mm wide hub.
