Rotor Direct Mount EMTB Chainring – Round | For Bosch Gen4

While in the design of chainrings a trend towards increasingly specialized, patented designs with correspondingly limited compatibility is apparent, Rotor goes the opposite way with the concept.

Thanks to the tooth form resulting from a complex development process, the eCHAINRINGs are suitable for a wide range of MTB chains. In line with the universal claim, the lightweight Direct Mount chainrings made of CNC-machined aluminum are also available for the eMTB drive units of common E-Bike manufacturers.
