Park Tool VC-1 - Valve Core Tool Tool,Blue, standard size

Nice machined quality tool, Pricey considering but does the job reliably.

If as I have, you have Presta valves with removable cores, this small lightweight tool is indispensable for both removing the cores so as to inject a tyre sealant into the tube or tightening the core up so it doesn't leak or fall out. The alternative is to use needle-nose pliers which, unless you are very careful, can risk destroying the thread of both the valve and the core. In addition, this tool will work with Schraeder valves as well, allowing you to repair them. It's small, lightweight and great value for money.

It’s suitable for purpose and good quality, but, as with Park Tool gear, it’s gonna cost you!

Arrived quickly and very easy to use much better than the one I have got so decide to keep it

Alive ridden bikes for 20 or so years now and never thought I'd need such a tool until one day I had a puncture and swapped it out for a new tube. Which I fitted in fast time and inflated and off I went, only to find after about an hour was deflating.That day I learnt 2 things, firstly always check that your inner tube cores are nicely done up to avoid the embarrassment that I had. Secondly this tool is so easy to use to tighten inner tube cores. We have al it of bikes at home and yeah you could use other tools too do the job but this was relatively cheap and dedicated to the job and so easy to use.Build quality as ever from park tools is amazing & this is so light it's easy to carry on rides

Handy size and very useful to check valves if you cant find a puncture

good quality tool - a bit too expensive in my view. Much needed if you use continental inner tubes where the valves always seem to undo with my pump. Does what is supposed to do

Great replacement for my plastic took that broke. Not the cheapest, but should last.

Muy buen producto práctico para quitar las válvulas de los tubbles

Recently I broke a presta valve when pumping my tire out on a ride. Though pricey compared to the competition, it is well finished, easy to use and very lightweight. It was a good feeling to know I had this in my tool kit along with a spare valve. Might be good to have a 3/8" socket or adjustable wrench just in case you have a stubborn valve. Unfortunately, I found out that not all presta valves are replaceable. In the description, there is a warning to that effect but did not notice this. For the most effective use of this product, probably good check your bike. You might have to replace the tube to use this.

Easy carryon while on the trail

Super Werkzeug, auch wenn es von Park tool ist, ist es nicht teurer wie bei anderen Herstellern.Einzige Verwirrung: Auf den Produktfotos ist es blau, in der Beschreibung steht aber grau.Zum Glück kam es bei mir in blau an, wie auf dem Foto.

I am very happy with this little thing. Park tool had it right once again.
