Ice-Tech
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.

Technology:
STI Dual Control (DCL)
DCL stands for dual control lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is probably more critical to the high standard performance than the added gearing. The shift internals borrow the robustness from the MTB technology and are so smooth, that effortless one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano total integration, and simply has to be experienced to be understood.

E-Tube
E-tube is a system platform in order to achieve the Di2 (Digital Integrated Intelligence) concept. E-tube transmits interactive signals and power supply to each electronic component by plug & play connection. E-tube is a no rust, no stretch, no freeze system and it ensures advanced low maintenance. E-tube project offers, besides customized setting of the electronic components, an update to firmware via Windows PC, tablet or smartphone. You have access to a range of options for a quick check of the electronic components or the system status.

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 bubble from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
