What Axle Do I Need?

The best way to find the axle for your bike is to input your information into our Fitment Selector here:

If our Fitment Selector did not list your bike, watch our YouTube video or follow these steps below:

 #1. Determine the length and thread pitch of your stock axle.

Most axles now come with the length (L) and thread pitch (TP) measurements printed on the axle. But don’t trust them, several companies are printing misleading information on the axle. Remove the axle from your bike and double check the dimensions.

 #2. Measure your axle.

No special tools required. Print our Fitment Guide (print actual size). 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.

 #3. Place your axle on the Fitment Guide to determine your axle’s length and thread pitch.

Thread pitch must match exactly. Determine if it is a 1.0, 1.5, or 1.75 thread pitch.
