Get Crisp Shifts with the Serpent 803136 Pulley Set

The Serpent 803136 pulley and shim set is designed to tidy up the shifting action on your vintage 720-09 GP model. By improving engagement consistency, it helps the two-speed transmission behave more predictably during acceleration and corner exits.

Main Benefits

Compatibility: Specifically matched to the Serpent Vintage Series 720-09 200mm GP models.
Precision Engineering: 21T design aimed at steady and repeatable gear transitions.
Durability: Constructed to stand up to regular track and club use.

Is installation DIY friendly?

Basic experience with two-speed gearboxes will make installation straightforward. Follow the model manual and check shim spacing and gear mesh during setup.

Will this change top speed or gearing?

The 21T pulley is intended to improve engagement rather than alter overall gear ratios. Any change in effective gearing will be minimal and depends on your existing setup.

What maintenance does the set need?

Keep the pulley and shim area free of debris, inspect for wear periodically, and relubricate where appropriate to preserve smooth shifting.
