ENVE Pressure Relief Presta Valve Stem Nuts - 2 Pack}
  • £9.99

ENVE Pressure Relief Presta Valve Stem NutsThese valve stem nuts come as a pack of two and are specifically designed to ensure that an improper tubeless tape set-up doesn't result in a damaged rim. If the tubeless seal between your tyre's air chamber and the rim's cavity is breached, the rim's cavity can become pressurised resulting in a pressurised rim and potential delamination of the rim's sidewall. These pressure relief valve stem nuts prevent this from happening by creating an escape for the air via fluted reliefs on the inner diameter of the nut. Air escaping from these ports, indicates a compromised tubeless seal.Recommended for all tubeless ENVE SES wheelsets as well as other brand road tubeless wheelsets.Features: Use: Road Size: Comes as a pack of two Manufacturer's Part Numbers: EN7201012Buy ENVE Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
