Shimano Ultegra ST-R8170 Front Hydraulic Disc Brake 12v 1700mm J-Kit Version (w/o Disc)

The redesigned Dual Control Ultegra ST-R8170 levers benefit from all-new ergonomics, even more precise braking modulation and wireless electronic shifting. These features allow you to focus on the next sprint, next run, or your partner’s next prank.

Shimano Ultegra ST-R8170 brake levers bring improved modulation and control to every ride using Shimano’s proven Servo Wave technology. The all-Di2 platform, used on both the Dura-Ace and Ultegra, allows for clear shifting, while delivering faster, more reliable wireless shifting.

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

J-Kit (Easy Hose Joint System)
On brake systems equipped with a J-Kit brake line connection, the brake lever has an integrated pinch joint (olive), which considerably facilitates the installation and removal of the brake line in its whole.
