A New Group. A New Day.

Shimano 105 Di2 is an ode to the magic that each new day brings. It shifts Shimano's perspective and inspires them to see the world anew, in all its glorious technicolour. It dares Shimano to ride out and find out what lies ahead. Shimano 105 Di2 borrows from top-tier Dura-Ace and Ultegra technology and functionality, wrapped up in sophisticated ergonomics. Unfold the four benefits of a new day.

Di2 Wireless Shifting

Shimano 105 goes wireless. Think lightning-fast precision shifts at the touch of a button without skipping a beat, even when fatigue sets in or you encounter an unexpected ascent. Going electronic also lets you shift under load, such as when climbing or sprinting. Customise how you shift. Shift without performance loss from Day 1 to Day 1000 and enjoy the silence to contemplate the world around you.

12-Speed Wireless - What a Difference a Gear Makes

Shimano's new 12-speed cassette is the same width as their 11-speed cassette so the space between each cog is narrower. This means shifts so smooth you'll barely notice them. Whether climbing, descending or rolling on the flats you'll keep your rhythm and stay in flow.

Wireless - Fewer Cables, No Clutter

Di2 is beautifully integrated into the design of the bike with no stretched or frayed cables in sight, or to replace. 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.

More Gear Range - It's All in the Teeth

The smallest cog of the 12-speed 11-36T rear cassette has 11 teeth while the largest cog has 36. This offers a big range of gears so you can climb hilly terrain or push on the downhills with superb control and ease. It might just be one tooth from 11 to 12-speed but smaller shifts, so small you'll barely feel them, bring a lovely rhythm and flow.

The Science of Speed

The next-generation Shimano 105 featuring Di2 draws on Shimano's design philosophy. The Science of Speed bringing fresh momentum, comfort and control. It lets you embrace an open road, full of infinite possibilities. Go deeper into your journeys. See the world in a fresh new way and enjoy the gift of each new day.

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.

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 or Full-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
