Comprised of Dual Control- style combination shift / brake levers, front derailleur, rear derailleur, and a battery pack, the new Dura-Ace Di2 7970 components add only 56 grams when compared to the full mechanical counterpart. The components have proven their capabilities this year in competition by top professional cyclists in the ProTour.
