Rotor Bike Components 1x13 Road Hydraulic Disc Brake Set Left

The 1x13 group offers a unique hydraulic shifting system with a chainring that is not only very lightweight and low-maintenance but also provides extremely reliable shifting performance under load.

The modular 1x13 system allows for flexible configuration for all applications. A wide range of various 13 and 12-speed cassettes, along with a large selection of oval and round chainrings, enables the perfect combination of gear ratios for any situation and challenge.

It can be switched between 13 and 12-speed and is compatible with Rotor 1x13 road bike brake shifters, Rotor 1x13 triathlon shifters, and the Rotor 1x13 MTB switch. The technology of the 1x13 derailleur is protected from shocks or foreign objects by a reinforced housing.
