Teravail Standard Tube - 700 x 20 - 28mm | 80mm Presta Valve

Why Do Aero Road Racers Choose the Teravail Standard Tube?

High-profile aero wheels with rim depths of 55mm or greater require a valve stem that can reach through the carbon without forcing the pump to fight a sunken connection, and the Teravail Standard Tube line delivers with a 80mm Presta valve stem built for the deepest road racing wheelsets available. Sized for 700 x 20-28mm tires, this tube covers the narrow performance road tire range where aero wheels are most commonly used, combining the correct tire fit with a valve length that works on everything from 50mm alloy training deep-sections to 80mm carbon race rims.

Teravail's butyl rubber construction maintains the high road pressures that narrow tires demand, resisting the slow pressure drop that can alter handling feel on a race wheel tuned to a specific PSI. The 80mm valve stem is also useful in non-race contexts: any wheel with a thick rim wall, a deep valve housing, or a recessed valve hole benefits from the extra reach, and this tube eliminates the headache of trying to thread a pump head onto a valve that barely clears the rim. If your wheels are deep enough to need 80mm, this is the tube that solves it.
