Shimano Dura-Ace 7900 10-Speed Chainset
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
Shimano has raised the bar to a new level of performance 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 for improved 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
Weight including bottom bracket 725g
