The Ultegra ST-R8020 dual control lever for front 2-speed derailleur and hydraulic disc brakes. Allows more accurate and precise shifting. It has a greater reach for adjusting your break and gear levers. The redesigned internal shifting unit ensures a quick and intuitive rear-shifting operation. When paired with the new FD-R8000 front derailleur, your front shifting will be even lighter. ST-R8020 adds an extra bonus in combination with the hydraulic disc brake: better rider control in all conditions. The small bracket size feels great on the palms and improves the ergonomics.

DUAL CONTROL LEVER
With shifting cable
Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.
When you pull a SERVOWAVE brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
The DURA-ACE/ULTEGRA/105 Dual Control Lever have an optimized structure with features that include the lighter weight pivot section in the near side of the shifting unit and the integral shifting cable for lighter steering. Its many component parts are made so compact and precise to achieve unprecedented high-speed performance.
