Shimano 105 Di2: It’s a new day

In 1982, Shimano 105 was launched to the cycling world, slotting beneath Dura-Ace and Shimano 600 Series (later rebranded Ultegra). The new road group quickly gained popularity as a budget-friendly platform that delivered high-level functionality trickled down from higher-end models. In the ensuing decades, Shimano 105 was updated seven times, each iteration providing ever-improving technology in an approachable package. 

This year, as Shimano 105 celebrates its 40th anniversary, the ultimate every-rider road group is getting the ultimate upgrade. Introducing the new Shimano 105 Di2 R7100 Series electronic shifting drivetrain, which once again delivers easier operation, increased reliability, and less maintenance in a more attainable package. Indeed, this eighth version of Shimano 105 signals a new day for the component line while staying true to the group’s original mission to bring affordable performance to more riders.




Now riders who have only used mechanical shifting systems can experience the function and technology inherited from recent ground-breaking updates to Dura-Ace and Ultegra. Shimano 105 Di2 R7100 Series is the culmination of years of research and development where flawless wireless shifting, tailored gearing, and an exceptional braking system mark a new era in affordable performance.

Never again will you skip a shift as you fatigue or encounter an unexpected climb. Instead worry-free Di2 shifting keeps you in control in any situation. This is a significant performance advantage over the course of a ride, saving you energy with every gear change and allowing you to focus on what really matters—your friends, your effort and the world around you. This is the ride you deserve.



Just as with its original groundbreaking electronic Digital Integrated Intelligence shifting system launched in 2009, this latest version of Shimano Di2 features critical functional enhancements, including a wireless cockpit and the jump to 12-speed. And it’s all been done without any sacrifice to the fast, precise and reliable shifting riders have come to expect from all Shimano road groups. Changing gears is simple and consistent all the time, every time.

Riders new to Di2 will be floored at how quickly and easily you can move from gear to gear, especially at the front derailleur. And don’t worry if you’re not mechanically inclined. Shimano Di2 is simple to set-up and maintain.

Battery life is also best-in-class, with a single charge of the main Di2 power source delivering approximately 1,000 kilometers of worry-free riding. And unlike other wireless electronic shifting systems, there is only one battery to charge and you never have to remove it from your bike for charging. (Smaller, replaceable CR1632 coin cell batteries located in the shift levers last 3.5 to 4 years. )
