Technologies

Servowave action
When the Servowave brake lever is operated, the initial cable recall is rapid, so a small lever travel is sufficient to bring the pads into contact with the disc brake rotor. Then the power multiplication factor increases rapidly at the contact between pad and rim, so more lever travel is used to apply more braking power with higher levels of control.

Ice Technologies
Shimano Ice Technologies components ensure more consistent brake performance by reducing heat buildup in the brake system. This helps prevent efficiency losses that can occur when brakes are applied repeatedly and vigorously in a short period of time, as happens along steep, long descents.

One Way Bleeding
The "ONE WAY BLEEDING" function was developed to ensure the quick and easy prevention of air infiltration in our hydraulic systems. We have optimized the whole oil circuit in the system to prevent air bubbles inside it.
The unidirectional oil circuit, together with a funnel tool with mineral oil, ensures an easy and clean bleeding system.
