Shimano Ultegra Crankset FC-6703 Triple HollowTech II Compatibility and Specs

Shimano Ultegra Crankset FC-6703 Triple 2011 series

Ultegra has long been recognized as a solid performer and thanks to Shimano's Systems Engineering approach the 6700 series continues to deliver. Lighter, more stylish and advanced by the latest Dura-Ace technologies, new Ultegra is a beautifully balanced group with optimal performance and specifications. Its unprecedented racing DNA takes shifting and braking to another level, with a with a weight reduction of 150g versus 6600 series.

The Shimano Hollowtech II technology continues as a bench mark in the crank and bottom bracket strength to weight category. The bearings are as far apart as possible, eliminating axle flex. Efficiency is also maximized because the bearings primarily carry radial loads resulting in lower overall friction and drag. The wider stance benefits bicycle manufacturers allowing extra real estate to fortify the bottom bracket area of the frame to keep flex to a minimum.

HOLLOWTECH II design : Optimum balance of lightweight and stiffness
New gear dimension for great improvements
Improved gear for less chain touch in small/ small combination
"HOLLOWGLIDE" outer gear : Hollow construction enjoys great rigidity and stability
