Shimano Ultegra Crank FC-6700 2speed 52/39 175mm grey
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.
Gradation: 39/52 teeth, 175mm
Wheight: approx. 785g
Bottom bracket not included.
