In my tubeless life I've had one flat that required a call-of-shame to my wife to pick me up. After that I started carrying a spare tube, which I have not needed and never looked forward to using because of sealant mess.
My friend sold his bike and gave me his Dynaplug repair kit with only one plug left. I ordered these repair plugs just to be ready for a puncture that is too big for the sealant and not big enough to require the tube (or the call to the wife).
Thankfully I have not needed them but it is good to know they are there.
My friend had success when he used the original plugs that came with the repair kit so I assume these will also work fine, And to clarify the headline, I DO know how they work. I just don't know IF they work. And I hope to never know. But I'm ready . . . just in case.
These things are wonderful. I rolled over a shard of glass and cut a hole in my rear tire 7 or 8 mm long. I tried the bullet tip plug, but couldn't force it in the hole. But 2 of the pointed tip size next to each other sealed it in a hurry. After filling it with an CO2 inflator it held air for several days until I replaced the tire. I'll never ride without the handle and some plugs.
I only wish the larger plugs came with a pointed tip.
I had two punctures during race and used the dynaplugs
Find the puncture, insert the plug with tool, pull out tool. Viola, its that easy.
Fortunately, I've only had to use one plug (pointed). Received a 4mm cut 1/3 distance between center tread and rim on a Schwalbe Pro One 700x25 mounted on a Dura Ace rim. Sealant wouldn't hold over 2.5 bars. Installed plug and it sealed instantly. Didn't have a blade to trim excess fibers so I just left them. Completed 60 mile ride without any loss of air. Trimmed fibers that evening. Plug lasted another 1000+ miles before it just stopped sealing, even with Stan's Race Sealant. Bought a refill pack of pointed plugs to make sure I wouldn't run short.
