The fact that the plug doesn't push through the tire and fall in or pull back out is key. It also happens to plug the hole very well especially with the large / small plug option. I have used it twice and both times the people I was with groaned like "oh man you got a flat we are gonna be here 20 minutes" and bam 45 seconds later we were rolling and they were all like "whats the link for that thing?!?"
Love the size of this! Easy to fit in saddle bag
Thankfully, I've not had a chance to try this but the size and build quality are great. The size and 4 pre-loaded plugs were the main reason for selecting this mode.
I use Dynaplugs on riding my road bike, I use tubeless tires on all wheels. The darts do become misaligned at times and need to be straightened.
These are likely the best tubeless plug system made today. Lightweight, compact, effective.....the best out there.
I've not used it, thank goodness, and hope I never do. But the size is perfect for carrying along on rides and it has several small and one large plugs, one of each are preloaded.
I like the design and weight of the dynaplug. Fortunately, I have not needed to try out the product. I am a road cyclist and hope it works if and when needed.
