Get the group coveted by professional racers for the ultimate in shifting performance. The shifting force required is very light and only requires about a 2mm movement of the paddles. Shifting can be done while coasting with the derailleur executing the shifts when pedaling resumes. The Di2 group keeps the low weight of 7900 because the weight of the battery is offset by lighter STI levers and no traditional cables.
