Description

The SHIMANO GRX 815 Di2 Right Lever and Rear Calliper is designed to deliver superior control and unrivalled precision on mixed terrain. Thanks to DUAL CONTROL Di2 technology, gear shifts are electronic, fast and perfectly synchronised via the SHIMANO Synchro-Shift system, guaranteeing a smooth and intuitive experience on all routes.

The advanced ergonomics of the lever ensure optimal comfort on long rides. Its raised hood head and finger indent maintain a stable position, whilst the non-slip texture of the brake lever offers excellent control, even on technical descents or rough surfaces.

On the braking side, the GRX BR-RX810 calliper adopts a compact Flat Mount design for elegant mounting and optimal control. Thanks to ICE TECHNOLOGIES technology, heat dissipation is improved, delivering consistent performance and precise braking.

The system integrates a J-Kit connector for simplified installation, quick access to adjustments, as well as a ONE WAY BLEEDING bleed, guaranteeing easy and clean maintenance. The GRX 815 Di2 combines performance, comfort and reliability to push your limits on all terrain.
