Serpent 903596 Lightweight 21T Pulley Adaptor - Race Drivetrain Upgrade  [SER903596]

Precision Lightweight Pulley for Competitive Racing

For builders aiming to sharpen on-track behaviour, the Serpent 903596 Pulley Adaptor is a compact upgrade that trims rotating mass. Machined for consistent tolerances and finished for smooth engagement, this 21T pulley adaptor supports cleaner drivetrain operation and helps improve throttle response across a variety of Serpent chassis.

Performance Improvements and Robustness

Reducing rotational inertia helps the drivetrain accelerate more readily, and this pulley adaptor is made to cope with the demands of regular track use while preserving consistent operation. Fitting the unit can yield better power transfer and more predictable handling under acceleration.
