Design cues & technical features taken from 7900 Dura-Ace components. The chainset has adopted the new hollow outer chainring & larger spacing between chainrings to allow a broader range of rear cassettes to be utilised. Key

Features: This Hollow Glide technology is claimed to save weight & increase rigidity for optimal power transfer & improve shifting under load. The Hollow Tech II 10-speed Ultegra chainset offers an ideal balance of light weight & stiffness, making it the perfect choice for both enthusiast & competitive riders. Hollow Glide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex & hugely improves shift performance, even under high load. The chainring teeth have been developed to work in conjunction with the CN7900 & CN6700 chains for increased contact to provide greater efficiency & enhanced power transfer. Industry leading Hollow Tech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight & improve strength. A wide range of chainring options & crank arm lengths are available to meet the needs of all riders & racing disciplines. Hollow Tech II integrated bottom bracket uses a wider bearing placement & larger axle diameter for increased stiffness & efficiency. Hollow Tech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling & increased durability. Weight: 785g (claimed including BB). Bottom bracket is not included. Also available as part of the Ultegra 6700 groupset.
