Product technical specifications

TECHNOLOGIES

J-Kit (Easy Hose Joint System) – For brake systems with J-Kit brake hose connection, the brake lever has an integrated squeeze seal (olive), which makes the installation and removal of the brake line much easier overall.

Dual Control Lever (DCL) – The Shimano DCL levers combine braking and shifting functions in one control unit for easy as well as comfortable operation. In raising the standard of performance, their innovative ergonomics are even more important to consider than adding additional gearing. However, the highlight of the STI shifters (Shimano Total Integration) shifters, is the ability to change gears front and rear with just one finger. The Dual Control levers owe this not only to an extremely precise and smooth operation, but also to the same stability for which Shimano's MTB technologies are already known.

Ice Technologies – In order to keep the braking power at longer continuous operation consistently high, Shimano has developed the Ice-Tech cooling technology for brake discs and brake pads. Brake pads with Ice Technologies feature cooling fins made of aluminum, which better dissipate heat. In conjunction with the optimized radiation properties of the rotor, this results in a longer durability of the pads, while brake noise and fading are minimized.
