1x13 Hydraulic Shifter

Brand: Rotor

The 1x13 hydraulic shifter is the lever that made the drivetrain possible: instead of pulling a cable or firing a motor, a single paddle on the right-hand lever simply pushes fluid through a 3mm hose, DoubleTap-style, while the gear indexing lives in the derailleur. It is an integrated hydraulic shift/brake lever, paired with Magura disc brakes, and shifts all 13 sprockets. Released in 2019 for road and gravel. Two notes on enum fit: the actuation is genuinely HYDRAULIC - mapped to the closest road integrated-lever key; and no 'ecosystem' key exists for ROTOR's proprietary hydraulic system, so SRAM (mechanical) is used as the least-wrong match because the single-paddle ergonomics resemble SRAM DoubleTap and the mech can convert to run SRAM 12-speed cassettes.
