With the same tooth configuration, the ratchet engagement area is increased by about 20%, lifting load capacity and realizing more stable and efficient power transmission.Larger contact area offers higher safety redundancy for ratchet operation and better running stability. The upgraded guide structure enables smoother and more accurate pawl meshing, bringing faster engagement response, less backlash and more direct power output feedback.Important NoticeThis hub is specially engineered for XC Cross-Country riding only.It is not allowed for Downhill, Enduro or any other high-intensity & high-impact riding. Over-limit application will cause permanent damage to bearings, axle and hub flange structure.
