Hobbyists seeking a precision drivetrain upgrade will find the Serpent 903596 Pulley Adaptor useful for trimming rotating mass. The 21T unit is finished to engage smoothly and assist consistent power transfer across compatible Serpent chassis arrangements.
Lowering the rotating weight helps the system accelerate more responsively and can produce a more direct throttle feel. The adaptor is built to endure normal competitive use while maintaining stable operation and efficient torque delivery.
