With a low-profile Flat Mount design, the SHIMANO ULTEGRA R8000 series hydraulic disc brakes provide greater control in all conditions without interrupting the aero lines of road bikes.
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.
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.
The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
ONE WAY BLEEDING
“ONE WAY BLEEDING” was developed for quick and easy prevention of air in our hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
