Control your speed with confidence. This Shimano hydraulic disc brake set includes the ST-RS505 levers with upgraded RS785 callipers, for powerful all-weather stopping with effortless shifting.
The increased stopping power is especially helpful when you are on the hoods and you adjust the reach and free stroke so you can get the levers just how you like them. Cooling fins on the brake pads offer excellent heat management on even the very longest alpine descents.
The STI levers feature vivid indexing which endures that each and every shift across all 11 speeds requires the same lever force. All Shimano brakes use mineral oil which is less corrosive and less hazardous than the DOT fluid found in most hydraulic disc brakes.
