Sometimes, there's just not enough space around the tire's valve stem for the gas station air chuck and hose to reach. Brake rotors, sprockets and saddlebags get in the way and keep the air chuck from making an airtight seal. The Valve Stem Extension is the remedy to this problem.

    This is a piece for convenience, I use it to check my tire pressure, and adjust accordingly. Before this, I would get all twisted up contorting, when it’s raining or wet out, this makes a simple job easier. Not a bad price either.

    Two star for the 8 weeks this item is back order, it should make filling up easier. I have leather bags and spokes.

    Makes it a lot easier getting to those valve stems on your bike - especially the rear wheel. I use it every time I check my tire pressure - a must have - I think.

    do the ends swivel or do i twist the entire extension to screw it on?
    jonny - 79735
    • Answer:
      Jonny, It is very simple--just screw the end on. The end should twist making it less work for twisting the entire extension. Thanks.

    What description
    Whatdoineedforauniquescre - Western PA
    • Answer:
      The Valve Stem Extension is approximately 13 inches long. The end that connects to the valve stem does have a swivel on it so you don't have to turn the entire valve stem extension to use it. Hope this helps . . . DRVMN

    will this extension work on the stem to the air shock filler also?
    Firedog10 - NY
    • Answer:
      This valve stem extension is equally as useless on the air shock filler as on a tire. You lose all your air trying to unscrew it. And that’s IF you’d been able to get it screwed on in the first place. It’s no easier to use than the chuck on an air hose.

        Hi Firedog10, Yes, this Valve Stem Extension is compatible with the Touring Suspension Air Pump. Thank you for your question.
