One of the key elements of the new Rotor 1×13 groupset is its modularity. With only a single rear derailleur, four 13-speed cassette options, and a single rear hub, you can mix-and-match with the remaining components out of Rotor’s existing offerings to build your complete lightweight hydraulic shifting & braking drop bar bike. Plus, you can even opt for four 12-speed cassette options to keep the initial cost down even lower…

Rotor 1×13 Availability

Rotor 1×13, 13-speed road bike hydraulic drivetrains

All of the new Rotor 1×13 road bike groupset are in production now, and will be available for purchase in April 2019, ready to be built into a modern 1×13 disc brake road, gravel, or cyclocross bike this spring. No word yet from Rotor on the availability of their new MTB flat bar trigger shifter that will bring 1×13 to mountain bikes as well.


  1. Is the 12 speed cassette the same spacing as sram?
    Like all 11 speed (camp, shim, sram) are all the same and wheels can be swapped.

  2. Are cassettes really going to cost up to $415? The component that is most changed on a bike. Way over the top. Seems that they want to price gouge on this component to make up for what seems to be a reasonable cost for the group sets.

  3. Can we please stop talking about how aero 1x is? It’s a big reach in my opinion. You lose a chainring but gain a massive cassette and long derailleur. Seriously getting sick of companies testing how gullible we are. At best it’s marginal. At worst, it’s the same.

    • You don’t need a long derailleur. The longer cage would only be to take up the extra chain in a wide ratio 2x system.
