Shimano’s commitment to broadening Ultegra’s appeal, as alluded to above in relation to the cassette, can be found here, too, in a choice of four ratios, each of which is compatible with the crank. 53-39 is intended for racing, the semi-compact 52-36 has been designed with sportive riders in mind, the compact 50-34 is for the touring market.
