Bring the top tier of electronic gear shifting to your gravel and adventure riding with the Shimano GRX 815 Di2 STI Lever.

Customise the functions via Bluetooth with your smartphone and fine-tune the fit with the reach adjustment.

Shimano GRX 815 Di2 STI Lever

The highest level of gear shifting performance from Shimano is now available to the world of gravel and adventure riding with this new GRX 815 Di2 STI Lever. Precision electronic shifting ensures that your chain moves sharply exactly when you need it and with Shimano's E-Tube platform you can wirelessly customise how the lever functions using Bluetooth®, even when out on the road. A raised hood keeps your hands locked in place so no matter how broken the surface slipping is prevented and control optimised, and this is complemented by a recessed finger notch and anti-slip texture. High braking efficiency means that only a smaller force input is required for greater stopping performance and modulation. Dial-in a fit to perfectly suit your style with the adjustable reach.

Please note, the image shows a right-hand lever.
