It just shifts — in the cold, the wet, all season long.
Electronic gravel shifting used to feel like a luxury. GRX Di2 makes it feel like the obvious choice: crisp, consistent and entirely unbothered by mud, ice or a fortnight away from a charger.
It just shifts — in the cold, the wet, all season long.
The ergonomics are the standout — the hoods are made for rough ground and gloved hands, and the shift logic never leaves you hunting. Battery life across a long tour is a non-issue.
It is a real investment, and a mechanical setup will get you everywhere for far less money. But once you have ridden a frozen morning where every shift still lands, it is hard to go back.
GRX Di2 is a wired electronic groupset available as 1×12 or 2×12, with hydraulic disc brakes, a group weight of about 2,610 g and around 1,000 km of range per battery charge. Shimano gives it a two-year warranty.
Best for set-and-forget shifting. Worth knowing: it is expensive to fit, the wiring adds set-up time, and it can be overkill for short trips.
