  • The EVO Slim line of gearboxes share many common parts with the EVO Shifter, including some of the weight relieved, all steel gears and aluminum plates. 

    This configuration of the EVO Slim accepts up to four AndyMark RedLine Motors for a significant power-to-weight ratio improvement as compared to CIM-based gearboxes. The ratios available for this gearbox are primarily optimized to be used with 4 in. diameter wheels.

    This gearbox is shipped in kit form, not assembled. The EVO Slim for RedLine ships with hardware to accept up to four am-3775 AndyMark RedLine Motors (not included.)

    Encoder Options:
    The EVO Slim for RedLine accepts either the E4T Optical Encoder Kit or the SRX Mag Encoder. When using the SRX Mag Encoder, use the SRX Magnetic Encoder Mounting Hardware Kit.
