VIVI Bike Freewheel Bicycle Cassette Sprocket

Precision-machined teeth and hardened steel resist the higher torque of electric-assist bikes, delivering quieter, more consistent shifts.

VIVI Bike Freewheel Cassette Sprocket

A robust replacement sprocket engineered to restore smooth gear engagement and prolong drivetrain life. The corrosion-resistant finish and precise spacing help maintain chain alignment under sustained assist, reducing skip and premature wear. Short commutes, loaded cargo runs, or steep assisted climbs all benefit from reliable tooth profiles that hold up to repeated stress.

Installation is straightforward on compatible freewheel and cassette hubs, making this a practical service-part for workshops and DIY mechanics alike.

• Hardened steel construction for improved durability under e-bike torque.
• Precision-machined teeth to ensure consistent, quiet shifting.
• Corrosion-resistant coating for longer service life in wet conditions.
• Compatible with many common freewheel and cassette setups.
• Easy installation for quick maintenance or replacement.

Swap in this VIVI sprocket to regain crisp shifting, lower maintenance intervals, and more efficient power transfer on assisted rides.
