ROTOR 1x13 - Unlock the world with just one chainring!
For the first time, the ROTOR 1x13 enables a 1x drive with the finest gear steps, maximum flexibility and bandwidth for any application!
The 1x13 group offers a unique hydraulic shifting system with a chainring that's not only light and low-maintenance, but also offers extremely reliable shifting performance even under a load that no 2x11/2x12 system can match.
The modular 1x13 system allows an extremely flexible configuration for any situation. A large range of different 13 and 12 compartment cassettes with a large number of oval and round 1x Direct Mount chainrings allows for the perfect combination of transmissions in every situation and challenge!
ROTOR 1x13 brake lever combination
The 1x13 is also compatible with existing ROTOR Uno brake levers, only the left brake lever has to be converted to a brake lever.
Light, robust and low-maintenance
The 1x13 not only saves weight but also provides an unprecedented level of reliability and low maintenance thanks to a closed hydraulic system. It offers all the advantages of a 1x drive with the full bandwidth of a 2x11 as well as an optimal cadence through fine gear graduation!
Revolutionary rear derailleur technology
The ROTOR 1x13 is designed around a drive system consisting of a revolutionary rear derailleur design, special 13-slot hubs with optimised wheels and modular cranks or power meters with 1x Direct Mount chainrings.
The precision handcrafted rear derailleur contains not only a clutch to minimize chain impacts on 1x drives, but also the gear indexing. It can be adjusted between 13 and 12 and is compatible with ROTOR 1x13 road bike brake levers, ROTOR 1x13 triathlon gear levers and the ROTOR 1x13 MTB Schifter.
The technology of the 1x13 rear derailleur is protected from shocks or foreign objects by multiple reinforced housing.
Aldhu 3D+ crankset
With the Aldhu 3D+, Rotor has developed a future-oriented road bike crank system that can be freely configured and assembled without special tools or specialist knowledge. Thanks to the Direct Mount System, the exchange of reeds is a matter of minutes when using the one-piece combination chainring or single reeds with Direct Mount Spider. Whether with round chainrings or oval Q-rings from Rotor, everything is possible and available in a wide variety. The Direct Mount System of the Aldhu 3D+ enables for the first time the fine adjustment of oval chainrings in 1-degree increments and thus an incomparable individualisation to personal requirements.
12/13 compartment cassettes
The high-quality and extremely light ROTOR cassettes are assembled in Spain CNC from 2 parts, which are milled in each case from the full block. Thus, an extremely low weight is achieved with the most precise function.
This set includes the group as 1x12 group, which is already 1x13 compatible! The right choice for all who want to combine a light, reliable, variable gear ratio 1x hydraulic shift system with existing Shimano 10/11-speed impellers.
