Shimano 105 R7100 Di2 Groupset A NEW GROUP. A NEW DAY. The new SHIMANO 105 brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience. With function and technologies inherited from DURA-ACE and ULTEGRA, SHIMANO 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, SHIMANO 105-optimized gear combinations, and an exceptional brake system, the new SHIMANO 105 marks a new era of affordable performance. Beautiful Minimalist Cockpit SHIMANO 105 Di2 brings a beautiful minimalist cockpit - free of wires and ports - that's more aesthetic and aerodynamic. Meanwhile the ergonomics of the all new dual control levers ensure superb comfort and control whatever your hand position. Something you'll especially appreciate on longer rides when fatigue sets in. Plus the shifters have over 3 years of battery life - so no worries there! Customisable Shifting Shift your way. Customise how you shift, the speed you shift and how many gears you shift in a burst via SHIMANO E-TUBE PROJECT Cyclist app, your smartphone and Bluetooth. You can shift manually or opt for SEMI_SYNCHRO modes - a bit like having your own personal shift assistant! Or you can stick to manual. Whatever you prefer! A Drivetrain for Diverse Riders Each component of the 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. A Brake System for All Conditions Slowing down never felt so good. Braking comes to 105 Di2 like never before and allows everyone to learn the joys of pushing their limits and braking. The brand new piston design of the hydraulic disc brakes means lighter, faster and smoother control - in all conditions. While the quieter braking system - with a 10% greater pad clearance than 105 R7070 disc brakes - won't disturb your ride in wonderland. Plus the simpler brake fluid bleeding process makes it more maintenance friendly.
