A DRIVETRAIN FOR DIVERSE RIDERS
Each component of our new SHIMANO 105 Di2 electronic drivetrain ecosystem has been meticulously engineered to work as one. Operating quietly in the background, it brings no-delay shifts with no loss of power to help you preserve your energy. You can also take on steeper slopes with the 11-36T 12-speed cassette in combination with the compact 50-34T crankset – the low gear you have always wanted. In fact, the compact crankset in front and 12-speed cassette in the rear offers ample set-ups for all terrains – from flat roads to rolling hills – and for all riders. What’s more, the narrow 12-speed chain ensures reliability.
