Presta Valve Core Pack

Presta Valve Core Pack

High quality replacement presta valve cores for all replaceable presta valve stems, tubeless and tubed.

The valves in a tubeless system have an important job of sealing and unsealing the stem so the air pressure can be adjusted with our pump. Over time the valves can become increasingly clogged with sealant making it hard to inflate and unable to register accurate tyre pressures. To keep accurate tyre pressure readings and pump up our tyres it is recommended to replace valve stems every 6 months while adding tubeless sealant with a Two 7 Performance Tubeless Sealant Injector on the new tubeless sealant service interval. All valve packs come with core removal tool to easily replace presta core valves.
