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. These industry leading HollowTech II cold forged hollow crank arms have evolved to increase rigidity, reduce weight, and improve strength.

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.

The chainring teeth have been developed to work only in conjunction with the CN7900 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.

The HollowTech II integrated bottom bracket design uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency. The bottom bracket's seal design has a minimal bearing interface giving superbly smooth rolling and increased durability.

Weight including bottom bracket 725 grams.

Note: Supplied without bottom bracket cups which must be purchased separately, See accessories below.
