The Ultegra BR-R8170 brake caliper has more clearance between the brake pads than the previous model, which prevents the brake disc from grinding and reduces noise. The braking performance of the two plastic pistons is designed for competition use, but is also suitable for leisure and training rides.
The Ultegra ST-R8170 shift/brake lever is powered by a CR1632 button cell that lasts for at least 1.5 years and can be replaced by you. It communicates via a wireless protocol with the rear derailleur, which in turn is wired to the battery and indirectly to the front derailleur.
- Cable length: 1700mm
- Gear levels: 2-speed, 12-speed
- Switching system: electronic, semi-wireless
- Brake type: hydraulic, 2-piston
- Brake medium: mineral oil
Data shift/brake handle:
- tidy cockpit, aesthetic appearance thanks to wireless connection
- wireless shifting, precise and fast (rear derailleur / front derailleur with wiring)
- unique ergonomics thanks to feedback from professional riders
- Servo-Wave technology for optimal brake control
- 16.4 mm grip width adjustment
- Firmware updates via E-Tube Project
- Connection with Shimano Connected partner devices from Garmin or Wahoo possible via E-Tube
- Brake lever and buttons painted
Brake caliper data:
- 10% larger brake pad clearance minimizes brake disc grinding, less noise
- Optimally tuned braking performance for racing and training use
- harmonious appearance and easy tool access thanks to Flat Mount
- optimized heat dissipation with Ice-Tech
- simple venting process
