Shimano Ultegra 6700 10-Speed 53/39 Chainset

The Shimano Ultegra 6700 53/39 Chainset HollowTech II is 10-speed and offers an ideal balance of lightweight 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 CN-7900 and CN-6700 chains for increased contact to provide greater efficiency and improved power transfer.

Industry leading HollowTech II cold forged hollow crankarms have been evolved to increase rigidity, reduce weight and improve strength. A wide range of chainring options and crankarm 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.
