In the cycling world you have normal flats and then you have the ride ending massive blowout. Small pieces of glass or metal found on the road often create a small puncture in the tire. Most of the time you can just put a new tube in, air it up and get back on your way. The puncture below came from a creek crossing that is pretty much a sidewalk with about ten rocks the size of small white powder donuts. Well, there was one really sharp guy in there I guess. This is something that tubeless sealant won’t fix. My tire went completely flat in two seconds. At this point most would be having a fun nature walk back to the car. I chose to use my Park tire boot along with a tube and ride the rest of the day. Pick one of these up next time you’re at the shop along with a spare derailleur cable and never walk to you car again!
