Shimano RS785 Hydraulic Disc Brake Caliper

Rim brakes are great, but they have an unfortunate penchant for not working well when it's wet, or when you don't squeeze them hard enough, or when a squirrel runs right out in front of you. Discs--we'll say it--are the future, and the Shimano RS785 Hydraulic Disc Brake Caliper is leading the charge. It's made to provide reliable, all-condition, fade-free stopping power when teamed up with Shimano's 11-speed ST-RS685 11-speed components, and features IceTech cooling fins, which are designed to dissipate heat, increase braking response, and keep performance high even during long, steep descents.
