EVO Slim - 2 Stage, 4 RedLine
The AndyMark EVO Slim for RedLine single-speed gearbox is a high performance, lightweight solution for a robust drivetrain gearbox. 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. The EVO Slim gearboxes ship with the am-0801a Toughbox Long Hex Output Shaft as standard, but teams can switch out the shaft for any other Toughbox Output Shaft (sold separately.)
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" diameter wheels.
