Looking to upgrade your drivetrain? Then look no further. The new Shimano 105 Di2 R7100 groupset brings Di2 shifting to a new affordable pricepoint. With functions and tech inherited directly from their DURA-ACE and ULTEGRA drivetrains, 105 Di2 is the culmination of years of research and development. Thanks to a shared Di2 platform, sophisticated ergonomics, 105-optimised gear combinations and an exceptional brake system, Shimano 105 Di2 marks a new era of affordable performance.

Going electronic also lets you shift lightning-fast under load – such as when climbing or sprinting, customise how you shift and change gear without performance loss. Wireless shifting brings a clean cockpit free of shift wires and ports. While the internal Di2 battery is concealed in the seat post or frameset.

The new 12-speed cassette is the same width as Shimano's previous 11-speed cassette, so the space between each cog is narrower. This means shifts so smooth you’ll barely notice them.

• Wireless Di2 Shift Levers for a cleaner cockpit with 3 year battery life
