Flat Tire Wednesday


Grr.  And on the new gravel bike too.  Just one of those little thorns that causes a slow leak.  You finish the ride, but overnight it leaks down and the next time you go to ride you get a flat surprise.

While patching I took a little time and installed an ancient set of Spinskins.  On the old gravel bike these reduced the flat rate from one every two weeks to one every decade or so.  (YMMV)  Too bad they're not made anymore.  However, looks like Panaracer is making something comparable, so if these poop out I'll pop for a set.

Or maybe just convert to tubeless.  Honestly for these little thorn-pricks, tubeless + sealant gives effortless protection on the mountain bike.  Damned mess though if you get a real slash.  Let's see how this goes.

BTW, wicked thorn.  Presta valve cap shown for reference, and those grid squares on the workbench are 1/2".

ps: Nah, my bike came with the cheaper wire-bead Knards.  Not tubeless ready.  Maybe next round of tires.
