The Lowdown: Dynaplug Tubeless Repair Kits

Tubeless bike tires are one of the best technologies introduced to mountain biking. Flats occur a lot less often as those thin, pesky inner tubes are eliminated from the system. And when the tire itself is punctured, Sealant inside the tire is usually sufficient to seal the hole.

But flats still occur with regularity on the trail as the sealant can't seal big holes or the sealant in the tire dries up and goes unchecked. So we've all been there, shaking the tire to no end hoping the sealant will plug the hole. And when all else fails, we pull out the inner tube of shame and step back in time and install the tube.

Full Review: Dynaplug Tubeless Repair Kits

The Dynaplug solution is indeed a novel one. At the heart of the system is a patent pending carrier that inserts a plug into a punctured tire. To do this, a brass tip connected to a tacky rubber plug is pushed in to the tire. Pulling the carrier out leaves the tip inside the tire and the plug to cover the hole.

The Carbon Ultralight kit come with a set of three plugs while the Micro Pro comes with five.

We've tested it in several situations and the seal is reliable indeed with or without sealant. Even on the sidewall, Dynaplug can be used as long as the structure of the casing is still intact. If the casing is cut or slashed, then all hope is lost.

The Process

The key to repairing a tubeless plug with the Dynaplug is finding the hole and inserting the plug before the tire is fully deflated.

The plug is inserted by pushing the brass tip plug with the CNC case.

At this point, the repair can be considered done as the plug will just trim itself after a few miles of riding. But the detail-oriented folks will want to trim off the excess plug.

One of the Micro Pro accessories is a sharp blade for cutting off the excess plug.

The Dynaplug when installed on the tire can be left by itself or cut for a clean install.

The Dynaplug system is a reliable one indeed. It is compact and works better than other repair kits on the market. It even works without sealant which is a great relief since there's no easy way to check sealant level in a tire short of opening it up and breaking the tubeless seal.

It may prove reliable enough for some that they may even choose not to carry a spare inner tube on some rides. And that is a great option for some specially with the weight of Plus tubes and Fat bike tubes.

This Carbon Ultralight version has less accessories but is more affordable at $25.

We appreciate having a very high end Micro Pro option available with all the bells and whistles for $55. But we think the $25 Carbon Ultralight is a great option for most folks.
