Shimano BR-R8170 Ultegra Hydraulic Disc Brake Set Rear

The redesigned Ultegra ST-R8170 Dual Control levers feature all-new ergonomics, even more precise brake modulation and wireless electronic shifting. These features let you focus on the next sprint, the next descent or your partner's next joke.

Shimano Ultegra ST-R8170 brake levers bring improved modulation and control to every ride using Shimano's proven Servo Wave technology. The all-new Di2 platform, used on both Dura-Ace and Ultegra, makes the controls clearly distinguishable, while offering faster, more reliable wireless shifting.

The BR-R8170 Ultegra caliper offers improved modulation, a quieter braking system and an easier-than-ever bleeding process. Despite its smaller size, the system is quieter than ever and simpler to maintain.

J-Kit (Easy Hose Joint system)
On braking systems equipped with a J-Kit brake line coupling, the brake lever features an integrated pinch joint (olive), making assembly and disassembly of the entire brake line considerably easier.
