I was nervous about running tubeless tires on my long rides because I Was afraid that a big hole would leave me stranded. I am talking about a hole, something a nail would make. Not the kind of little pin prick that comes from a wire. The sealant handles that with no issue. And it sort of handles a nail hole, but these plugs make is seal right up. And this little tool kit fits on a jersey pocket, So the saddle bag can really be eliminated. ( If you dare). I still carry a tube, just in case. But only one. And if you have a tube, you need tire levers. And if the tire gets a big cut, like I did, then you will be glad you have the tube. But really, this thing is amazing.
Fortunately, I haven't had to use this product yet but I do feel more secure by having it in my seat bag. The item is very small & takes up little space and has multiple plugs contained. It is expensive thus my 3 star value rating.
I got a sizable hole in my tubless tire during a pre-ride at a 'cross race. I thought my day was done before it started! I went to the neutral service tent and the mechanic pulled out a PILL. He had me install the plug and use the saw to cut the excess rubber. Presto! The tire held air and I was able to race without any tire problems. I was sold, so purchased a PILL that now comes with me on rides I use my tubeless tires. The PILL gives me more confidence I can fix future holes in my tubeless tires!
If you've ever had to break the bead from the rim on a tubeless tire in order to insert a tube while on the road you'll certainly appreciate the Dynaplug Pill. Several weeks after receiving the Dynaplug I had the opportunity to use it and can attest that it works as advertised. The repaired tire is still on the rim, plug and all. I was fortunate that not much air had yet escaped from the punctured tire but the sealant wasn't stopping the leak. It takes a bit of pressure to insert the plug but once inserted - no more leak. The Dynaplug Pill seems expensive until the cost of a new tire is factored into the equation, and it contains extra plugs to make multiple repairs. The product is small, taking up little room in the jersey pocket or saddle bag. If you're riding tubeless tires this a product you should consider.
