Overview

This Carbon-Ti X-Lock EVO is a front thru axle made for Fox Boost forks with 110mm hub spacing. The axle is 15mm in diameter and 155mm long, with an M14x1.5 thread. It is machined in Italy from 7075-T6 aluminum with a flat head, and it weighs 34.5 g. It is color anodized, in the color you select.

Why we love it

We love a part that quietly does its job better than the one it replaces.

  • 01At 34.5 g it is machined with a variable wall thickness that keeps the front end stiff without excess weight.
  • 02The flat head and laser etched graphics keep a Fox fork looking factory-clean.
Why it makes the cut. Hammer & Howl only carries parts we believe are among the best in the business. This axle is a well-made detail for a Fox Boost trail or cross-country fork.

Confirm before ordering

If you are not sure this axle matches your fork, confirm with your bike mechanic or contact Hammer & Howl before ordering.

Newer model years and other forks may also fit, so confirm your fork’s axle specification against the dimensions above. Despite the 15mm axle diameter, this axle’s thread is M14x1.5, which is how Fox builds these forks. A thru axle must match your fork in diameter, thread size and pitch, length, and head shape. The simplest check is to remove your original axle and compare its stamped size and length, or ask your fork’s manufacturer for the specification. Your hub also needs an internal axle sleeve for this axle to pass through.

Questions

How do I check this axle fits my bike?

Remove your original axle and compare its stamped thread size and overall length, or ask your fork’s manufacturer for the axle specification. The diameter, thread size and pitch, length, and head shape all need to match.

What does the internal-axle requirement mean?

This axle needs a hub built around an internal axle sleeve. If your hub is an open design without one, this axle does not work with it; check your hub’s specification before ordering.

Why is the thread M14x1.5 when the axle is 15mm?

Because that is how Fox designs these forks: the axle shaft is 15mm in diameter, and the threaded end steps down to M14x1.5. Your original axle uses the same combination, so compare against it before ordering.

Is a tool included?

No. This axle mounts with a 6mm hex key, which most multi-tools include. No tool ships in the box.
