Shimano Ultegra FC-6703 Crankset - Triple - 52/39/30T

by: Shimano

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
    • Bottom bracket not included
