Shimano GRX Di2 Wireless

The Shimano GRX Di2 Wireless is the first wireless groupset designed specifically for gravel riding. Running a 1x configuration, it offers a 510% gear range and 700–1,000 km battery life. Shifts are fast and it is backward-compatible with existing frames, though the rear derailleur looks bulky and the mechanical derailleur hanger remains a weak point.
