Shimano GRX 820 Di2 set, cranks 175 mm, cassette 11-34T, 2x12
Electronic 12-speed novelty from Shimano designed specifically for gravel bikes. The GRX Di2 kit combines unrivaled electronic shifting with an optimized gear mix for everyday driving, racing and all-day adventure.
New levers with excellent ergonomics communicate wirelessly with the derailleur and derailleur. The shape and position of the lever allows for easy and safe braking even with one finger while gripping the handlebars.
Flat Mount GRX brakes are smaller, thanks to 10% more space between the disc and the pads, they are quieter and bring a faster onset of the braking effect with easy dosing.
The electronic derailleur has a low weight of only 315 grams. It communicates with the shifter wirelessly, but is connected to the main battery by cable, which gives it a long life on a single charge. It is intended for cassettes in the range of 11-36 teeth. Pull switching allows you to choose the optimal chain tension for gravel or road.
The GRX twin chainrings have a range optimized for gravel wheels, as does the twelve-speed Ultegra CS-R8101 11-34 cassette.
The GRX kit includes the following components:
- brake / shift levers Shimano ST-RX825
- Shimano BR-RX820 Flat Mount calipers
- derailleur Shimano GRX RD-RX825
- derailleur Shimano GRX FD-RX825
- cranks Shimano GRX FC-RX820-2 175mm 48x31z
- cassette Shimano CS-R8101-12 34 teeth
