Description
Shimano brings their innovative Dura-Ace chainring design to the Ultegra FC-6700 crankset for even better power transfer at a more affordable price. The unique hollow chainring results in a stiffer and lighter crank. Updated wider spacing between two rings eliminates the possibility of chain rub even in the small/small gear combination. Standard and Compact versions with rigid and lightweight Hollowtech II arms.
