As a late adopter of tubeless riding, I have to say I'm now a convert. These work and are so much simpler than changing a tube, or worse, having to patch one on a ride. I still carry a spare tube as a backup for the worst case scenario. One thing that people don't mention is that you will get more punctures riding tubeless. A sharp object only needs to puncture the tire when tubeless, instead of both the tire and the tube with a traditional setup. You'll notice it when you see a wet spot from the sealant seeping out until it seals and at first this is unsettling. If I notice a spot after a ride I'll rotate the tire so that the spot is at the bottom to allow the sealant to pool over the spot. The next day if the tire is low/flat or still seeping sealant I'll use a Dynaplug.
Used the kit for the first time on the side of the road so I was not sure how successful the repair would work out, but it worked far easier than expected. Added some Co2 and finished a 40 mile ride with no sealant leakage. Can't say enough about the ease of use.... works as advertised
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.
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.
This past August I had 3 potential flats that sealed up on my rear tire, but required a plug when I got home. The Dynaplug plugs are easy to install and work perfectly. I highly recommend their use.
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.
