The SHIMANO ULTEGRA R8020 series shifters bring greater rider control in all conditions thanks to SHIMANO's category-leading hydraulic disc brakes. Lighter front shift action and refined ergonomic shape sweeten the deal.
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.
Free Stroke
The distance from initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences.
