Surly Front Thru-Axle

This axle is designed for forks with 12mm thru-axle dropouts and 100mm hub spacing. Before purchasing, verify that your fork requires a 12x100mm standard and check your current axle's thread pitch, as this model uses a 1.0mm pitch.

The thread pitch refers to the distance between the threads on the axle. It is critical that this matches your fork's dropout threads exactly; if the pitches do not match, the axle will not thread in properly and could damage your fork.

No, this is a dedicated thru-axle component. It is engineered specifically for 12mm thru-axle systems and will not fit or function with standard quick-release dropouts.

Chromoly steel offers an excellent strength-to-weight ratio and superior durability compared to many aluminum options. This makes it a reliable choice for riders who prioritize structural integrity and long-term performance over shaving every possible gram.

Yes, the 112mm measurement is the total length of the axle from the tip to the underside of the head. Always measure your existing axle's total length to ensure this replacement will seat correctly in your specific fork.
