Inline valve extenders for tubular tires or tubes with removable presta valve cores. Simply use the included tool to remove the valve core, thread the extender into the valve base, and then thread the valve core into the open end of the extender. The rubber o-ring seals the assembly but teflon/plumber's tape can be used for an even tighter seal. The assembly works just like a normal presta valve and adds 50mm or 70mm to the existing presta valve.

easy to use extender
Extremely good valve extender, especially needed for tubular tires. It has the increased flexability of moving the valve itself to the extender making refilling and not needing to refill tubulars as often.
