Know before you buy
No, this axle is specifically engineered for the X-12 system with a 142mm over locknut dimension and a 1.0mm thread pitch. You must verify that your frame's dropout spacing and thread specifications match these measurements before purchasing.
The patented RWS (Ratchet Wheelmounting System) uses a ratcheting lever mechanism that allows you to achieve higher clamping force than a traditional cam-style quick-release. This results in a stiffer interface between the wheel and frame, which improves handling precision on technical terrain.
Yes, as long as your frame uses the X-12 standard and requires the same 142mm spacing and 1.0mm thread pitch. It is a direct replacement that offers a tool-free, more secure way to remove and install your rear wheel.
Yes, the RWS lever is independent of the clamping mechanism. Once you have tightened the axle to your desired tension, you can pull the lever out and rotate it to your preferred position without affecting the clamping force.
Yes, the axle is constructed from high-grade aluminum designed to withstand the rigors of mountain biking. Its robust build provides the necessary stiffness and security required for demanding trail conditions.
