Shimano Ultegra BR-R8170 Hydraulic Disc Brake Caliper - Flat Mount - RW

Shimano Ultegra BR-R8170 Hydraulic Disc Brake Caliper - Flat Mount - RW

 

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 BR-R8170 disc brake caliper

All around improved, the Shimano Ultegra BR-R8170 caliper offers optimised dosing, quieter braking performance and extremely simplified maintenance.

While a faster-gripping initial braking force always gives the feeling of full control, the 10 % increase in brake pad spacing allows for a significant reduction in noise during braking, despite a flatter overall construction. In addition, when the RT-MT900 brake disc rotor (sold separately) is used, its deformation-resistant design, even with increasing heat, helps to create an extremely quiet and smooth braking system.

To simplify maintenance, the hydraulic 2-piston brake caliper not only features the proven One-Way-Bleeding system, but also a separate arrangement of bleed nipple and opening screw. On the one hand, this minimises the risk of the bleed kit hose slipping off when opening or closing the system and, on the other hand, makes it unnecessary to dismantle the caliper from the frame for bleeding process.
