Technologies:

- SERVO WAVE: When you pull the SERVOWAVE brake lever, the initial stroke of the pads is rapid, so a slight movement of the lever is enough to bring the pads into contact with the brake disc. The power multiplication factor then increases rapidly at the "pad/rim" contact point, so that the lever travel is used to apply more braking power with greater control.

- Reach Adjust: The brake lever has a reach adjustment mechanism. You can adjust the distance between the handlebars and levers to fit any size, respecting the rider's preferences.

-DCL: DCL means DUAL CONTROL LEVER. It incorporates brake and shifting functions into the system and allows for easy operation.

Technologies:

- ONE WAY BLEEDING has been developed for quick and easy prevention of the presence of air in the hydraulic system. They streamlined the path of the oil in the system to avoid air bubbles in the system. The one-way oil path, plus a funnel tool for mineral oil, provides an easy and clean purge system.

- ICE TECHNOLOGIES: Overheating, which can occur in the disc and pad when braking on long descents, has a negative impact on braking performance. Shimano has adopted ICE TECHNOLOGIES brake disc to realize cooling technology that ensures reliable performance. The coated disc blade, with a three-layer sandwich structure of stainless steel, aluminum and stainless steel, provides better irradiation performance.
