Dura-Ace means simply best and here is the best group-set they make but with the advantage of three chain wheels, to make any mountain ride able, with the style and class of the same equipment that the top professionals of the world use.
Designed from the 7800 Dura-Ace series, the triple is designed with those seeking a wider gear range and the prestige of the Dura-Ace name. The chainset, bottom bracket front and rear gears and the STI gear/brake levers are made specially for the triple groups-set, the rest of the equipment is the same as the double group-set.
The Dura-Ace bottom bracket has super power transmission with optimum balance of lightweight/rigidity and minimal bearing inerface for smoother rolling, mated with the triple crankset, with 52-39-30 teeth chainwheels and seven different lengths in a one-key release and hollow crank arm technology.
The front and rear gear derailleurs are made of lightweight alloy and sealed bearings and with the STI levers makes precise and accurate shifting every time. The other components in the group-set are tried and tested by the best riders in the world and are the best you can buy.
