ULTEGRA R8100 Di2 - EVEN FASTER
High speeds come with great responsibilities. That's why we took a holistic approach, focused 100% on performance, to make the new ULTEGRA groupset even faster. Whether you're competing in local races, breaking your personal record, or sharing the pure pleasure of riding with friends, our new 12-speed road groupset offers unrivaled control and comfort, all day, every day. This is the Science of Speed. This sets Shimano apart from the competition.
CLEANER COCKPIT
The new and elegant wireless cockpit offers simplicity, clean aesthetics, improved ergonomics and simplified maintenance. And this thanks to the new wireless system that we have developed to make shifting even faster, without sacrificing precision and reliability. Road cycling has never been so enjoyable.
SMOOTH AND LIGHTNING SHIFT
Shimano's innovative instant shifting offers a smooth and intuitive experience for road cycling. The revolutionary HYPERGLIDE+ technology allows you to tackle climbs, sprint or simply train without having to think about the next gear change. The new Di2 shifting system uses our exclusive wireless technology to offer the fastest and most precise shifting on the market. And the battery life is also best in class, the centralized internal battery offers approximately 1,000 kilometers of worry-free driving on a single charge.
THE MOST REVOLUTIONARY TRANSMISSION SYSTEM IN THE WORLD
The ULTEGRA R8100 groupset is our fastest and most inspired drivetrain in this class and offers truly revolutionary innovative features. HYPERGLIDE+ technology enters the world of road cycling for the first time. The new Di2 shifting system uses our exclusive wireless integrated circuit. And switching to a 12-speed cassette gives you all the gear range you need. A first for ULTEGRA, the power meter takes Shimano power data accuracy to a new, more accessible level. Ergonomics and aerodynamics have been optimized throughout. And of course, you can set the drivetrain just the way you like with Shimano's easy-to-use E-TUBE app.
OPTIMIZED BRAKING CONTROL
Quieter and smoother, the new ULTEGRA braking system offers even more precise modulation and braking control in every situation, thanks to Shimano's proven SERVO WAVE ACTION technology and improved brake lever ergonomics. With simplified maintenance, completely revamped hydraulic disc brakes offer a perfect balance of speed control and stopping power. And the new brake caliper design minimizes rubbing. ULTEGRA brakes can handle any tour de force, and let you focus on the next sprint, the next descent or the conversation with friends.
