Along with the levers, this is the component that has seen the most striking changes from earlier Ultegra - again as a result of Dura-Ace technology trickling down. The outer chainring is hollow rather than solid, making this both lighter ad stiffer than its predecessors. In fact, Shimano claims to have increased stiffness by 20 per cent over previous Shimano designs, and having ridden and raced using this chainset we've no reason to disbelieve this statement - it does feel incredibly stiff. And another area where this scores is the price. The chainset and bottom bracket combo weighs just 39g more than the Dura-Ace, but comes in at less than half the cost. An absolute bargain.
Features:
The HollowTech II 10-speed Ultegra chainset offers an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders
HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load
The chainring teeth have been developed to work in conjunction with the CN7900 and CN6700 chains for increased contact to provide greater efficiency and improved power transfer
Industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight and improve strength
A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines
HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability
Weight including bottom bracket 785 grams
