Shimano Ultegra FC-6700 Road Crankset

You'll love the super-stiff, premium-shifting platform of the lightweight Shimano Ultegra FC-6700 crankset. The crankset features Hollowglide technology; a hollow, wide-profile outer chainring that saves weight and increases rigidity for optimal power transfer and improved shifting. Super-smooth outboard bearings are spread as far apart as possible to eliminate axle flex. The bearings primarily carry radial loads resulting in lower overall friction and drag. This crankset requires external BB cups that are sold separately.

The Ultegra 6700 crankset comes in two basic flavors, standard and compact. Compact is known by the number FC-6750. The standard, 130mm bolt circle diameter version comes with a 39/53 combination. The compact, 110mm bolt circle diameter version comes with a 34/50 chain ring combination. The crankset, in both versions can be had with either 170m 172.5, or 175mm crankarms.
