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.
I always have a variety of Dynaplugs available in my seat bag. They are very useful for temporary patching punctures in tubeless tires that are too big for the sealant in the tire to handle. I am a ride leader on club rides and use them for my own tire and for others on the ride that need them.
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.
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
Great that I have them now..... Hope I never have to use them..... Wished Id had them countless times previously.
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.
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.
I've been riding road tubeless for a decade and this system is the only one that works every time. The reamers with bacon are unreliable at best. This works!
