Shimano GRX ST-RX810 Shifter

Shimano Index System

Servo Wave Action  – 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.

Reach Adjust – 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.

Dual Control Lever (DCL) – DCL stands for DUAL CONTROL LEVER. It has brake and shifting functions in the system and enables easy operation.
Ergonomic innovation is probably more critical to the higher standard performance than the added gearing. The shift internals borrow the robustness from our MTB technology and are so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of SHIMANO TOTAL INTEGRATION, and simply has to be experienced to be understood.

Ice Technologies – 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 – developed for quick and easy prevention of air in their hydraulic system. Shimano have 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.
