We spotted a new Shimano GRX mechanical 12-speed gravel groupset at Unbound 2023 on the Pivot Vault of Shimano-sponsored rider Taylor Lideen.
While we only saw a mechanical groupset in a 1x drivetrain arrangement, that was enough for us to hazard a guess as to the direction Shimano may be heading in.

We have good reason to suspect a 12-speed mechanical version of […]
