THE ULTEGRA BR-R8170 BRAKE CALLIPER BY SHIMANO - MORE SPACE FOR BRAKE PADS
With the Shimano BR-R8170 flat-mount brake caliper from the Ultegra road bike groupset, the brake pads have more free space than with the predecessor model, which prevents grinding of the brake rotor and reduces noise. The braking power of the two plastic pistons is tuned for competition use, but is just as suitable for leisure and training rides. In addition, BR-R8170 features a simple bleeding process thanks to One-Way Bleeding technology. The two-piece caliper design is made of lightweight aluminium and comes with Ice-Tech resin pads, which ensure particularly good heat dissipation thanks to their cooling fins. However, you can also ride it with conventional pads.

TECHNOLOGY
One Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.
