Greater safety on any road - Gravel-optimised ergonomics
The GRX brake levers have a robust non-slip coating to ensure greater grip and control even in heavy rain, splashes and mud. The non-slip surface of the GRX hand guards guarantees constant control, even on the roughest descents. The non-slip surface of the GRX brake levers guarantees Shimano's legendary stopping power at all times, even in the presence of water or mud. The new shape of the GRX RX820 handguard distributes pressure over a larger surface area of the hand, maximising comfort on long rides.
Slowing down has never been so pleasant - race-ready braking system
The GRX BR-R820 disc brake calliper offers new levels of control, with improved modulation and a more immediate braking attack point. And despite its smaller design, the system is quieter than ever and maintenance is easier. (pads are included).
