Information
Shimano Ultegra FC-6703 Crankset
With the same technology as the Dura-Ace 7950, the new Ultegra triple crankset uses a hollow outer chainring to save weight and boost rigidity for optimal power transfer and positive shifting under load.- Hollowtech II design uses a wider bearing placement to maximize stiffness while keeping weight to a minimum - what you get is a dramatically stronger pedaling force with better power transfer, acceleration and speed
- HollowGlide hollow outer chainring reduces weight, increases strength and enhances stiffness of the entire crankset by 20% for even more shifting power
- Wider gear range accommodates most cycling situations and offers less chain touch in the small/small combination
- Individually machined chainring teeth improve chain contact for greater shifting performance
- Improved bottom bracket seals reduce contamination and friction
- Bottom bracket not included
- Shimano Ultegra FC-6703 Crankset should be used with the Shimano Ultegra CN-6600 10-speed Chain
