  • 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.

  • Light weight butyl rubber construction.
  • Super light at only 82g
