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, 13-speed road bike hydraulic drivetrains
Rotor has predetermined four standard kits at retail launch that will suit the four most likely types of rider that will want to put 1×13 on their road, gravel, or cross bikes. Each gives you the flexibility to pick the gear ratio you need, and all of the benefits of tight gearing spacing, smooth cadence steps, light weight, single ring simplicity & reliability.
Rotor 1×13 Ultimate Performance kit
“For competitive riders who track their performance and that are looking for climbing capacity with a lighter, more aero, and reliable groupset than the traditional 2×11 set-up. The perfect choice for those looking to enhance your cycling performance with the most sophisticated power meter in the market.”
This $4900 / 4500€ kit includes all of the new 1×13 group, plus a Rotor 2INpower direct-mount road power meter crankset with a direct mount chainring, and a new set of carbon wheels with the 13-speed compatible Rotor Rvolver hubs.
Rotor 1×13 Super Light kit
“For high performance riders who want a super light ride for sprints, attacks, mountain passes and high-speed descents with an optimized gear sequencing for demanding climbs. Disc brake designed high-performance carbon wheels a Super Light experience that will exceed all your expectations in lightness and maximum performance.”
This $3800 / 3450€ Super Light kit gets all of the same new 1×13 group components and the carbon Rvolver-equipped wheels, but swaps in a simple & light ALDHU direct-mount road crankset (NO power meter).
Rotor 1×13 Adventure kit
“For competitive cyclists who want a light and reliable hydraulic system with an optimized gear sequencing and wheels built for comfort and durability. 1×13 has been designed to strike the perfect balance between lightness, precision and durability with aluminum wheels to withstand the most demanding pedaling conditions.”
This $2800 / 2600€ Adventure kit brings cost down a big step again, with the complete 1×13 group & ALDHU direct-mount cranks, but with an aluminum set of Rvolver-equipped wheels for 13-speed.
Rotor 1×13 Compatible kit
“For cyclists who want to upgrade their current transmission with a reliable hydraulic 1x system and the option to easily upgrade your hubs, wheels and cassette to 13s at a later stage. 1×12 is the entry point to the ROTOR 1×13 platform and our affordable 1×12 cassettes offer you a gear range similar to 2×11 with a lighter, more aero and reliable combination without changing chainrings at any time.”
Lastly, the 1×13 Compatible kit for $2200 / 2000€ isn’t actually 13-speed at all. It includes the shift/brake setup, 1×13 derailleur & alloy ALDHU cranks, but gets a 12-speed cassette that will fit on your existing wheelset. Then if you want to go 13-speed down the road, you can always swap in the 13-speed cassette once you buy a compatible wheelset (or rear hub.)
