Shimano BR-RS785 Hydraulic Disc Brake Caliper with Resin Pads with Fins, Front or Rear

Rim brakes are great, but they have an unfortunate penchant for not working well when wet or when a squirrel runs right out in front of you, so we look to the Shimano RS785 Hydraulic Disc Brake Caliper for reliable, all-condition, fade-free stopping power. It teams up with Shimano's ST-RS685 11-speed components for added performance and features IceTech cooling fins designed to dissipate heat, increase braking response, and keep performance high even during long, steep descents.
