To raise the performance standard, their innovative ergonomics are even more important than adding extra gears. The highlight of STI (Shimano Total Integration) controls, however, is the ability to shift the front and rear gears with a single finger. Dual Control levers achieve this not only through exceptionally precise, smooth operation, but also with the same stability for which Shimano's MTB technologies are already known.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eSERVO WAVE |\u003c\/b\u003e Because the brake lever takes up a large amount of travel at the start of its movement, the brake pads contact the rotor more quickly, leaving more lever travel to modulate braking force. As a result, SERVOWAVE braking systems offer a faster response, higher performance, and shorter free stroke.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eJ-Kit (Easy Hose Joint System) |\u003c\/b\u003e On braking systems with a J-Kit brake hose connection, the brake lever has an integrated seal (olive), making the brake hose easier to install and remove.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eIce Technologies |\u003c\/b\u003e To maintain consistently high braking performance during prolonged, uninterrupted use, Shimano developed Ice-Tech cooling technology for rotors and brake pads.
