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 higher standard performance than the added gearing. The shift internals borrow the robustness from Shimano's MTB technology and are so smooth and effortless that 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.

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

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

Brake fading during prolonged uninterrupted operation, e.g. downhill, impairs braking performance. Shimano has introduced brake discs and pads with Ice-Tech technology to create a cooling technology for consistently high braking performance. The brake rotor has a three-layer stainless steel sandwich structure on the outside around an aluminium core. It radiates heat better and reduces a surface temperature from 400° C to 300° C, for example. The brake pads also have optional cooling fins. The design of the rotor in combination with the cooling fins results in a longer service life of the pads, less braking noise, less fading and a lower weight.
