Shimano Ultegra R8110-RS Seatstay Direct Mount Rim Brake Caliper

Shimano Ultegra R8110-RS Seatstay Direct Mount Rim Brake Caliper Shimano’s Ultegra R8110-RS Rim Brake Caliper is for use with frames that have a seatstay direct mount fitting option for the rear brake. The lightweight aluminium construction keeps the weight down and has sufficient clearance for use with larger 28c tyres whilst the Super SLR-EV Dual-Pivot design keeps the action light and consistent; with increased power from the improved brake arch proportions. The brake shoes use replaceable cartridges to make replacement easier and cheaper with convex washers enabling a simpler toe-in setup.
