Description

The left SHIMANO GRX ST-RX820-LA lever, paired here with the BR-RX820 front caliper, belongs to the 12-speed generation of the GRX RX820 range. It integrates the hydraulic brake lever and dropper seatpost control into a single unit, for a clean cockpit suited to single-chainring drivetrains that require only a conventional brake/shift lever on the right-hand side.

The hood ergonomics follow the characteristics of the GRX range: a raised cover and textured surface limit hand slippage, a non-slip coating covers the brake lever, and the hood body has been optimised for flared handlebars specific to modern gravel riding.

The BR-RX820 front caliper, with Flat Mount mounting, provides improved modulation and a quicker bite point thanks to SERVO WAVE technology, for precise, quiet braking with maintenance made easier by the One Way Bleeding bleed system. The dropper seatpost control operates via an Optislick cable with low galvanic coating and a 10 mm pull stroke. A reach adjustment system, operated with a 2 mm Allen key, allows the lever position to be adapted to hand size and riding style.
