The Hollow Tech II 10-speed Dura-Ace chainset offers the optimum balance of light weight & rigidity, making it the global choice for road racings 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 & increased weight savings by trimming unnecessary material. The ultimate aluminium chainset, even lighter than many carbon chainsets. Key

Features:
The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load. These industry leading Hollow Tech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, & improve strength. The teeth have been developed to work in conjunction with the CN7900 chain for enhanced contact providing more efficiency & enhanced power transfer. There is a wide range of chainring ratios & crank arm lengths available enabling customisation for all riders & racing disciplines. Hollow Tech II integrated bottom bracket design uses a wider bearing placement & larger axle diameter for increased stiffness & efficiency. Weight: 739g (inc. bottom bracket
- Manufacturer claimed). Bottom bracket cups are sold separately.
