Shimano's XTR Rear Hub is World Cup-worthy, with an unmatched race pedigree. The hub shell is manufactured from cold-forged aluminum for exceptional strength, and it uses a Titanium freehub body for light weight and tough-as-nails performance. 36 points of engagement means the hub responds instantly, with direct power transfer to the rear wheel and lightning fast acceleration. A 12mm thru-axle makes a stiff and responsive rear wheel with great stability and durability, and Shimano's trademark angular contact bearings roll smooth, fast. And, the hub uses Shimano's Center Lock rotor mount to make swapping rotors super easy.
