For all bikers for whom a 1×12 setup does not offer enough bandwidth or the gear jumps are too rough, Rotor has the solution with the 1×13 drive. With 4 different 13- or 12-speed cassettes, you can optimally adapt your drive to your needs. While the 13-speed setup hubs with the widened rotor freewheel bodies are required, the 12-speed rotor cassettes can be mounted on conventional Shimano MTB freewheel bodies. In addition, the circuit set is also ideally suited for the use of SRAM Eagle 12-speed cassettes. The switching commands are transmitted via a completely closed hydraulic system. This makes the rotor switching group extremely reliable and low-maintenance. No worn and dirty Bowden cables or discharged batteries can slow you down. The only 3 millimeter thin, flexible line that is also suitable for Shimano Di2 cable guides ensures simple internal laying of the hydraulic line. Weighing just 451 grams (unabridged), the 1×13 rotor set is at eye level with the shifting components of SRAM’s electronic Eagle XX1 AXS group.
