June has seen a lot of action from Shimano. We’ve covered a brand new Shimano XTR groupset, the first ever wireless groupset from the Japanese giant, and hot on its heels was the launch of the lower-tier Deore XT wireless groupset.
Both of these groupsets were all-new; a systemic overhaul, which kind of explains why Shimano decided to clean-slate both ranges at once. Now Shimano has released a new GRX wireless Di2 groupset, but unlike XTR or XT it’s not really a new groupset at all, but rather a combination of a new rear derailleur and a new left hand shifter that, in combination with current component offerings, can create a fully wireless, 1x gravel groupset.
