Shimano 105 ST-RS505 + BR-RS785 Ice Tech w/Fins Hydraulic Disc Brake w/Shifter Dual Control Lever Kit 11 Speed. Pre-bled Caliper, Brake lever, and Pre-Bled hose.

Optislick cables feature a minimal and uniform electrically coated layer that improves routing efficiency and provides excellent corrosion resistance.

Servo Wave
When you pull a Servo Wave brake lever initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.

One Way Bleeding
One way bleeding was developed for quick and easy prevention of air in Shimanos hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in it. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.

The fade, which can occur to rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technology rotors and Ice Technology pads to realize the cooling technology for consistent performance. The rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400 °C to 300°C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the rotor blade and the radiator fin provide long pad life, less noise, less fade and are lightweight.
