Shimano Dura-Ace 7900 10-Speed Double Chainset

With a unique four-arm spider and Hollowtech II construction putting strength just where its needed, the FC-9000 chainset sets new standards for stiffness and low weight. The HollowTech II 10-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders.

Features:

  • Shimano has raised the bar to a new level ofperformance with the development of a hollow outer chainring, giving vast improvements in rigidity and increased weight savings
  • The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load
  • These industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength
  • The teeth have been developed to work only in conjunction with the CN-7900 chain forimproved contact providing more efficiency and improved power transfer
  • There is a wide range of chainring ratios and crank arm lengths available enabling customisation for all riders and racing disciplines
  • HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
  • Bottom bracket seal design has a minimal bearing interface gives superbly smooth rolling and increased durability
  • 11-speed compatible
  • Weight including bottom bracket 725 grams

A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
