With the Shimano BR-R7170 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-R7170 features a simple bleeding process thanks to One-Way Bleeding technology. The two-piece caliper design is made of lightweight aluminum 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.

One Way Bleeding is a technique used on the brake caliper that makes it easier to bleed the brake. The hose routing has been optimized so that no air bubbles remain in the brake caliper. In combination with the funnel, the brake can be bled cleanly and easily.
