Shimano Di2 got better, and faster, with the Shimano Ultegra RD-R8150 Di2 Rear Derailleur. We notice the smooth and quick shifting up our 12-gears of range no matter what conditions exist. The derailleur works with up to a 34t cassette that allows for plenty of low gearing range for the biggest climbs in our backyards.
