Shimano FH-9000 Dura Ace Freehub Rear Hub

• 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 giving 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
  
• Weight: 247g
