Innertube with a Presta valve

Innertube with a Presta valve

This innertube is available with a Presta valve, also known as a French valve. This is essential for road and touring bike enthusiasts. This valve type handles high pressures, but when inflating the innertube with this valve you need to open the valve by unscrewing the nipple on top. It's a go-to choice for cyclists seeking efficient and reliable inflation for their high-performance rides.
