Shimano Dura-Ace 9000 Rear Hub | Silver - Aluminium - 28 Hole

This is the Shimano Dura-Ace 9000 36 Hole Rear Hub. Elite road racers demand the best - Dura-Ace components are precision engineered for ultimate performance and durability. Improved Freehub body design for quick pawl engagement for instant power transfer. Oversized axle has increased rigidity torsionally and laterally removing axle flex when under compression from the quick release, thus improving rotational smoothness and durability. Labyrinth double contact sealing - low-friction seals effectively shut out water, mud and dirt without affecting rotational smoothness. Borozon treated bearing races - super mirror finish bearing races reduce friction providing silky smooth and precise bearing rotation. Cold forged and machined aluminium hub shell and oversized 7075 alloy axle combined with a titanium Freehub body all keep the wheel weight to a minimum. Quick and easy bearing assembly and maintenance via a simple to use digital click adjuster removing the need for cone spanners. 8, 9, 10 and 11-speed compatible titanium Freehub body.
