    Remove a Stan's presta valve core with a cheap spoke wrench

    While adding sealant to my tires today, I came up with an easy way to remove the cores from my Stan's presta valves. I tried several different searches and couldn't find the same solution documented anywhere. Hopefully I'm not the last one to the party.

    Although the official presta valve core removal tool doesn't cost much, I always forget to add one to my order. When it comes time to add sealant I don't have it and I end up removing the cores using a small adjustable wrench. C'est la vie.

    I was gathering up a few tools and noticed the cheap-o spoke wrench in the back of the drawer.

    It looked about the right size so I gave it a try.

    The "11" slot fit almost perfectly. I spun the cores out, refilled the sealant and spun them right back into place. Oh, so much better than the small adjustable wrench.

    I've seen these spoke wrenches at just about every LBS for only a couple of bucks. If you're lacking the proper tool this might just help you out in a time of need.

    Unfortunately, my valve core didn't fit my spoke wrench, so I had to make my own "tool".

    Here I am with a bunch of stock aluminum and this never occurred to me.

    Nice job! Now I'll probably make something similar just to have in my pack.

    I use a spoke wrench for that too.

    marpilli - this just blew my mind. I am going to give this a go for when I do my ghetto conversion this weekend. Last time I tried, I ended up with Stans everywhere. I have now forgotten how much of a PITA it was, and am going to try again, this time armed with even more research.

    Funny; I've always thrown those "universal" spoke wrenches away, since they suck so much for spoke nipples. Great find.

    This worked great for me. In addition, the "9" slot worked well for installing the valve extenders on my tubulars. The 11 slot is a little loose for the valve core but it works okay anyway.

    It's interesting that the 11 slot fit well on the valve cores I have. I somehow doubt those cheap spoke wrenches are made to exacting measurements.

    Dumb question on my part, what are the numbers supposed to indicate? Is there some "standard" numbering for spoke nipples?

    I'll take a guess that it has to do with the gauge of the spoke itself, being made to fit the standard nipple size. Might not be accurate for all spokes.

    I use a teeny tiny ignition wrench. Don't remember the size but IIRC it is the 2nd from the smallest in a Craftsman fractional set.
    I may or may not be laughing at you.

    that is correct, it's the gauge of the spoke

    I've learned something new today. Thank you, both.

    Another great idea. I have a set of those wrenches in standard and metric. Never occurred to use them for this.
