Nice!
While I was in there, another guy came in with his super tricked out mtb and needed his rear tire replaced. Maxxis Ardent 2.4", a tire I already use on one mtb and like a lot. He popped out for a few minutes and I watched the other mechanic on duty rip the old tire off, drop it in the trashcan and get to work setting the replacement up tubeless. I asked "is that a 29?" "yup" "um, can I have it?" "yeah, I guess so". I was grabbing it out, but then the other mechanic said that the guy had mentioned it had a sidewall tear, so I dropped it again. Good thing, because when that other customer came back he asked for his old tire so he could give a try at patching it. Would have been awkward all around if I had to fish it out of my backpack!
