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. Improved gear for less chain touch in small/ small combination. HOLLOWGLIDE outer gear : Hollow construction enjoys great rigidity and stability. NOTE: FC-6703 cranksets should use CN-6600 chain.
