Ultegra Di2 Goes 12-Speed

Shimano's brand new Ultegra R8170 Di2 12-Speed Groupset is the fastest, most technologically advanced Ultegra group to date. The backbone of the new groupset is Shimano's game-changing HYPERGLIDE+ shifting technology. First introduced on Shimano mountain bike groups, this unique chain-and-cassette interface smoothly guides the chain up and down the cassette for effortlessly crisp and precise shifting in both directions — even under extreme pedaling load.

Here is what's new:

Evolved Di2 Platform – Completely redesigned Di2 system for Shimano's fastest shifting ever in addition to a wireless cockpit design for the best performance and reliability possible.

Advanced Drivetrain – Optimized 12-speed gearing for unrivaled efficiency and Shimano's proven HYPERGLIDE+ technology for seamless shifting no matter the situation.

Refined Interface and Ergonomics – The ultimate balance of comfort, aerodynamics, and aesthetics, Ultegra R8170 offers unparalleled ergonomics and a cleaner cockpit design.

Enhanced Brake System – Ultegra's updated braking offers a quieter, maintenance-friendly system with improved control.

What's Included

  • FC-R8100 Hollowtech II 2x12-Speed Crankset — The Ultegra 12-speed crankset comes as a 50/34T double with your choice of 170, 172.5, or 175mm crank arm lengths.
  • CS-R8100 12-Speed Cassette — The Ultegra 12-Speed Cassette comes in a 11-34T configuration. The cassette is compatible with Shimano 11-speed freehub bodies or the new Shimano 12-speed freehub body.
  • RD-R8150 12-Speed Rear Derailleur — The Ultegra RD-R8150 rear derailleur is updated with Shadow technology. Shadow tech is made with a low-profile design and single tension construction, so the derailleur does not hit the chainstay in rough riding conditions. The result is smooth and silent performance.
  • FD-R8150 Front Derailleur — Combining Shimano's new Di2 platform and the road incarnation of HYPERGLIDE+, the Ultegra R8150 front derailleur shifts between chainrings with the fastest, most seamless action on the market.
  • ST-R8170 Shifters — Shimano's new Ultegra ST-R8170 shift and brake levers bring enhanced modulation and control to every ride by employing Shimano's proven SERVO-WAVE technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering the world's fastest, most reliable wireless shifting.
  • BR-R8170 Flat-Mount Brake Calipers (160mm Front, 140mm Rear), Resin Pads, & Hoses — The Ultegra R8170 disc brake caliper brings a new level of control to the road cycling world with enhanced modulation and a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.
  • RT-MT800 Ice-Tech Disc Rotors (160mm Front, 140mm Rear)— Shimano's Deore XT RT-RT800 compact and lightweight disc brake rotors feature rapid heat dissipation thanks to ICE TECHNOLOGIES FREEZA heat management system.
  • Ultegra/XT CN-M8100 12-Speed Chain — This ultralightweight chain has 126 links for 12-speed drivetrains and features an included Quick-Link for easy installation and removal.
  • Di2 EW-SD300 Electric Cables, BT-DN300 3-Port Battery, & EW-EC300 Charging Cable — The battery has been improved for extended life. It comes with 1 x 900mm and 1 x 1200mm Di2 cables.
