Ultegra R8100 – Leave Time Behind

When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere – whether in an everyman race, on the hunt for a personal best time or on a companionable ride.

As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.

Shimano Ultegra shift/brake set consisting of the electronic ST-R8170 STI lever for lightning-fast shifting and the hydraulic BR-R8170 disc brake caliper for superbly controllable and quiet braking. Trouble-free maintenance is provided by the proven One Way Bleeding concept and the Easy Hose Joint System which simplifies brake hose exchanges.

Features

  • High performance Ultegra Wireless hydraulic Servo Wave disc brake Di2 STI's give you control, modulation and power with minimal effort in all riding conditions
  • Wireless connectivity to the front and rear derailleurs for effortless trouble free gear shifts
  • With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
  • Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences.

  • Drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI
