The Ultegra FC-R8100 crank not only converts your pedal force into propulsion, with its high rigidity it also ensures extremely fast and precise switching behavior. The high switching precision is supported by the optimized chainring design. In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II construction of the crank arms. The crank is available with a gear ratio of 52-36 teeth and 50-34 teeth and with crank arm lengths from 160 to 175 millimeters.
