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.
