The Ultegra 6800 chainset is the most striking addition to what must be said is a highly attractive groupset. It’s the obvious beneficiary of the trickle down model employed by Shimano
With reduced weight (765 grams with the largest 53-39 tooth setup and bottom bracket) with no loss in stiffness.
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
