Optimize drivetrain performance with Serpent 401980

For RC builders aiming to sharpen their Medius X20 Mini EP, the Serpent 401980 Midshaft Pulley 21T is a precision spare that helps refine drivetrain behaviour. It is designed to reduce friction losses and extend component life during spirited track runs.

Core benefits of the Serpent midshaft pulley

  • Compatibility: Engineered to fit the Medius X20 Mini EP chassis exactly, allowing a straightforward swap with no extra machining.
  • Durability: Produced from robust materials to handle repeated track sessions and demanding driving styles.
  • Performance: The 21T configuration provides a balanced mix of torque and speed, aiding throttle response and control.
This pulley is made for the Medius X20 Mini EP and fits that chassis without modification. Other models may require different dimensions or adaptors, so check fitment before fitting.
Installation is straightforward with basic tools. Remove the old pulley, confirm alignment and gear mesh, then secure the new pulley following standard servo and drivetrain checks.
Inspect teeth for wear, keep the area free of grit, and check bearings regularly. A quick clean and light lubricant will help longevity between services.
The 21T tooth count shifts the torque and top speed balance compared with other sizes. To alter gearing further, pair different pinion or spur options and retune gear mesh accordingly.
