Barbieri Presta 40 mm valves squared base
Pair of quality Barbieri PNK tubeless valves (2) are ideal for converting to a tubeless set up;
Valve length: 40 mm
Base: Squared 12 x 8mm
Color: Polished Silver / Black plastic valve cap
Removable valve core allows for easy tyre sealant filling
12 x 8 mm rubber base makes an air-tight seal by screwing the valve ring, compressing the rubber firmly against the rim.
Squared base suitable for deeper/narrower rims where a circular base won't fit.
Fits most tubeless ready bicycle rims.
