700x18-25c Presta 42mm Valve Superlight

  • Lightweight allowing you to massively reduce your rotating mass. Every gram counts at the rim to improve acceleration!  
  • We use butyl not latex (like some lightweight tubes) meaning this tube holds air extremely well.
  • This size of inner tubes is used on road and triathlon bikes.
  • Presta valve type (AKA High Pressure Valve or French Valve).
  • Removable and replaceable valve core.
  • Threaded valve stem with security ring prevents rattling on the rim and makes pump attachment easier.
  • 42mm length valve suitable for most standard depth rims up to 30mm.
  • Reinforced dual thickness tube/valve interface to prevent punctures.
  • Light weight butyl rubber construction.
  • Super light at only 82g
