The Legion VMax High Volume Valve Converter allows you to convert standard presta valves to become high volume Vmax valves.
These valve converters are a must have if you are riding tubeless or if you want to make inserting tyre sealant easy.
To use tubeless tyres you need to seat the tyre as quickly as possible and presta valves by design are not high volume. Vmax valves deliver 300% more volume, enabling tyres to be seated with a track pump.
Can use existing valve stem.
1 size fits all M6x0.6 Stand rims threads
1 size for all rim depths
Can be fitted to inner tubes to allow sealant be added
The original valve must have a removable valve core.
