Description
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.
