Shimano
Description
Increasing speed comes with great responsibility. That's why Shimano has taken a 100% performance-oriented approach to making the new Ultegra 12-speed groupset even faster. Whether you're competing in regional races, trying to beat your personal best or riding for the sheer fun of it with friends, this new groupset offers unrivalled control and comfort, all day, every day. It's the science of speed. The
Shimano Ultegra R8170 groupset boasts the fastest, most inspired drivetrain on the market, and is packed with innovative features that reshuffle the deck. HyperGlide+ technology hits the road for the first time. The new Di2 shifting system features Shimano's exclusive wireless integrated circuit.
At the same time,the switch to a 12-speed cassette ensures that you'll have the full development range you need.New to the Ultegra groupset, the power sensor takes Shimano power data accuracy to a new, more accessible level. Ergonomics and aerodynamics have been improved across the board. And, of course, you can configure the drivetrain the way you like it via Shimano's user-friendly E-Tube app.
Quieter and smoother, the new Shimano Ultegra braking system lets you enjoy even more precise modulation and stopping control on every ride, thanks to Shimano's proven Servo Wave Action technology, and improved brake lever ergonomics. Easier to maintain, the completely redesigned hydraulic disc brakes balance speed control and stopping power like never before, while the new brake caliper design limits the risk of friction. With even better braking, the Ultegra groupset lets you focus on the next sprint, the next descent or conversations with your riding buddy.
