The Presta Valve Adapter for Schrader Drilled Rims lets riders safely use Presta inner tubes in wheels originally drilled for larger Schrader or Dunlop valves.
Key Features:
- Adapts a larger Schrader/Dunlop valve hole to the correct size for a Presta valve.
- 6 mm inner diameter provides a close fit around the Presta valve.
- 8 mm outer diameter fills the oversized valve opening to reduce unwanted valve movement.
- 11 mm wide by 20 mm long flat support section sits securely inside the rim.
- Flat section fits easily between spoke holes, including on smaller wheel sizes.
