Shimano Dura-Ace FH-7900 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 (125% faster than previous Dura-Ace) 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 and 10-speed compatible titanium Freehub body
• Supplied with Q/R skewer
