Q & A

Dura Ace:

The HollowTech II 11-speed Dura-Ace chainset sets new standards for both low 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. The new four arm design actually delivers the same stiffness but with less weight, putting strength only where it's needed.

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 CN9000 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.
