Wolf Tooth Rear X12 Thru Axle

This axle is specifically designed for the X-12 standard with a 1.5mm thread pitch. While it fits 142mm hub spacing, you must verify that your frame specifically uses the X-12 thru-axle system before purchasing.

The captive steel washer is designed to reduce friction against your frame's dropout. This allows the tightening torque to convert directly into clamping load, which keeps your wheel secure while preventing the axle from seizing or galling over time.

This is a high-precision upgrade manufactured to aerospace standards. It is built for enhanced durability and smoother installation compared to many standard-issue axles, which can sometimes be prone to seizing or wear.

Yes, it is standard practice to apply a light layer of bicycle-specific grease to the threads before installation. This ensures smooth operation and helps prevent the axle from seizing in the future.

No, it is designed to be installed using a standard hex wrench. It functions as a direct replacement for your existing X-12 axle, so no proprietary tools are necessary.
