Shimano Ultegra R8170 Disc Brake Front Caliper

Shimano Ultegra R8170 Disc Brake Caliper Front Part of Shimano’s latest Ultegra groupset; the R8170 Front Disc Brake Caliper provides great control and modulation thanks to the opposed 22mm ceramic pistons. Heat insulation and dissipation on long; technical descents are helped both by the ceramic material and the fins on the resin pads; ensuring that power is consistent and fade-free all the way down. Designed to work with 140mm or 160mm rotors using the adapter; the fork-mounted caliper is compact and lightweight; yet now offers 10% more pad clearance than the previous iteration to reduce the chance of rotor contact. Ease of maintenance is also improved; with the one-way internal fluid circuit making bleeding simpler and the use of non-corrosive mineral oil brake fluid.
