I had a flat today on the Mt Fromme fire road on my Procore'd rear tire that sealant wouldn't seal. I'm guessing it might have been too cold and wet out.
Long story short, I couldn't get the locknut on the Presta valve undone with only my Crank Bros M19 Multi tool, until I finally hammered the 10mm "wrench" opening onto it pretty much mutilating it. Finally got a tube in it after screwing around with it for an hour in the freezing rain.:swearing:
What's the lightest / most compact tool anyone has found to carry along on rides for this purpose? I'm thinking a really compact and light pair of plyers or are there other options?
