Hydraulic shifting? 13 speeds? What in tarnation?
That’s what was going through my head when I first saw Rotor’s 13-speed drivetrain kit at Sea Otter last year. The 1×13 kit is a follow up to Rotor’s Uno 2x groupset from four years ago. Like the Uno, the 1×13 uses hydraulically-actuated shifting for a groundbreaking industry first. As you might imagine, this tech is pricey, and probably not for everyone, myself included, but over the past few months, I’ve enjoyed riding it on this beautiful titanium chassis by none other than Merlin Bikes. Check out a full review of Rotor’s 1×13 and the Merlin Sandstone Gravel bike below.
