The HollowTech II 11-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 11-speed HG-EV chains for increased contact to provide greater efficiency and improved power transfer. Industry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weight. 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.
Please Note: Not supplied with a bottom bracket

Great Shimano product! What can you say, Shimano builds the best components in the market. Nothing finicky about the set up and top quality out of the box. Worked fine with my non 11 speed chain. Probikekit had the package out the door and delivered quickly state side so no complaints there. Great service!
