Dynaplug Review: Micro Pro Tubeless Tire Repair Kit

Ever heard of the Dynaplug tubeless tire repair kit? If not, you should. The size of a Mini-Bic lighter, the Dynaplug Micro Pro is the best tire repair accessory we’ve had the misfortune to try…

With a proper tubeless setup, and generally tough tires, it’s not often that you have to resort to tire plugs. However, in my opinion, they are an indispensable part of a proper bikepacking repair kit. Relying on spare tubes alone introduces the risk of pinch flats, small punctures, additional patches… and the prospect of having to carry your bike out of the backcountry should your options run out — which I have experienced. I typically carry five or six of the reddish brown strips and the tiny screwdriver handle tool to insert them. In the event of a small tear, they work. But they require some finesse, super glue, and often equally as much frustration and swearing. Someone pointed out the Dynaplug as a superior solution, so I decided to give it a try.

In essence, Dynaplug is designed to be a quick and easy puncture repair tool for tubeless tires. The crux of the patented system is a two-piece aluminum body with a hollow stainless steel insertion tube that’s threaded into the handle. The tube is preloaded with a repair plug where it sits in place, ready for action. The repair plugs are each made of a proprietary rubber-impregnated cord mounted to a pointed, non-abbrasive brass tip.

This silver Dynaplug Micro Pro tool rattled around my frame bag and backpack for months prior to our trip in the Republic of Georgia. Even though I hadn’t had a chance to test its merit, I decided to bring it along, untried, hoping that it would work in the event of a tear big enough to thwart the efficacy of tubeless sealant. Fortunately I was unlucky enough to be able to try it, three times…

At first glance, the plugs seem a bit odd; the sharp brass tips don’t look like something you’d want sticking inside your bike tire. However, according to Dynaplug, if the brass tip breaks free from the plug, there is nothing to worry about. They chose brass because it’s a soft metal that will wear down over time, and brass is inherently non-abrasive to tire rubber. Based on centrifugal testing they found that the tip will eventually disintegrate, without causing further issues. This never happened during our testing period, but it seems like it having the brass piece bouncing around inside the tire could be rather annoying if it did occur.

At any rate, function is more important than form. Each brass-tipped plug is designed to offer a permanent fix for punctures up to 4.6mm (about 3/16″) in diameter. In the event of an emergency, Dynaplug states you can use up to four plugs at once for larger tears, although they also mention that a proper repair should be made once available. It’s also worth noting that they offer rounded, ‘bullet-tipped’ plugs as well.

Dynaplug Micro Pro or Pill?

The Dynaplug comes in several different configurations. The two we checked out are the most popular, the lozenge-shaped Dynaplug Micro Pro and Dynaplug Pill. Both are housed within the same 6061 machined aluminum capsule. The two halves thread together and are sealed by an O-ring. Both contain the same attachments, although the Pill is anodized and costs $5 more. The tool itself, albeit small, seems rather excessive based on its contents. The honeycomb of cavities inside the casing store an assortment of odd accessories and pointy brass-tipped plugs. Both the Micro Pro tool and Pill contain two pointed tip tire repair plugs within two insertion tubes, one micro knife, one air stopper. The tool also comes with three additional plugs and one pipe cleaner. First off, I never used the ultrasharp awl-like air stopper or the pipe cleaner. The air stopper is to be used to seal the air leak while preparing the Dynaplug. But each time I’ve used the tool, there was a tear significant enough to drop most of the pressure pretty quickly, before I could access the tool. However, this might come in handy for large thorns where you might ‘swap’ out the thorn for the stopper. But in my experience, Orange Seal does a pretty good job plugging such holes without a plug. Regarding the other tools, the knife can be used to trim the excess ‘tail’ from the plug once inserted — which Dynaplug recommends – and the pipe-cleaner is for cleaning the insertion plug should it get clogged.

The Dynaplug in Action

Performing a repair with the Dynaplug is ridiculously simple. Gone are the days of fiddling with the little plastic handled insertion tool, with sealant spewing everywhere during the process. The visco-elastic material that makes up the plug works quickly and the tool is relatively easy to use. The plug is preloaded into the insertion tube that’s already screwed into the handle of the tool. So you simply unscrew the two halves and push the plug into the puncture. Once the tool is removed, the squared edges of the brass tip catch inside the tire leaving the super sticky rubber-impregnated cord to adhere to the puncture edges and expand to seal the leak. Each time I used it the leak was sealed immediately without a lot of tire spinning and ensuing panic. We used it twice in Georgia for two small rips a little over 1/8″ that required just one plug to seal immediately.

The most recent use was back home in Pisgah, as shown in the photos below. Gin hit a rock and tore a hole in the sidewall of her tire, a little less than 1/4″ wide. Not having the Dynaplug immediately on hand, she tried a ‘classic’ strip plug; it didn’t seal the tear. Later on, after her ride was shortened, we pumped up the tire and applied finger pressure to the tear to hold in some of the air. We then quickly inserted and removed the Dynaplug and it sealed right up. Since the repair, Gin has been on several trail rides on our local rooty and rocky singletrack around Pisgah without any issues. This is the third time we’ve used it and each was successful, sealing the puncture with plenty of riding afterwards to prove it. All in all, I have found the Dynaplug to work like a charm and plan on making it a staple in my kit from here on out.

Pros

  • The Dynaplug system works like a charm based on our review period. We’ve sealed up three tire rips, both in the sidewall and tread area, all of which held up afterwards for many additional miles of riding.
  • It’s very light and easy to carry.
  • The Pill and Dynaplug Micro Pro Tool are compact… perfect for bikepacking.
  • The preloaded tube is quick and neat compared to fiddly plastic insert and gummy ‘classic’ orange plugs.

Cons

  • It’s kind of expensive, although it will probably last a long time, and it’s made in the USA.
  • It would be nice if it held more plugs in lighter plastic tubes within the capsule.
  • The brass tips are slightly concerning, although I have heard of no complaints or failures. Plus, you can get rounded ‘bullet-tipped’ plugs as well.
  • The pieces rattle around a little inside the shell, but I stuffed a cotton swab in there and that solved the problem (cotton swabs have always been a staple while bike touring… vibrations kill).

    My local bike shop guys brought these to my attention about a year back. Love, love, love them. Used twice, worked flawlessly. Although I did have one of the metal tips fall off the plug inside my tire and rattle around for a couple days. No damage, just a bit of a pain in the butt to remove.

  • Yeah, I agree… I am sold on it, for sure. Interesting to hear that one of the tips fell out. I assume you broke the seal and removed it? Did it make a lot of noise?

  • Harley Raylor

    Is this appropriate for use on a lighter weight tire such as a compass tire in the 44mm wide range

  • Dylan

    why don’t they just make the tips out of plastic that would degrade much quicker than brass? Surely a plastic tip would be enough to get the plug in there, and would likely disintegrate or at least round off much quicker than brass…

  • I wondered the same thing. According to the company, “We chose brass for the specific reason that it’s non-abrasive to the tire.” I would think a hard rubber or plastic would also be compatible, but I am not a materials engineer, so perhaps there is a reason that they didn’t go that direction. Either way, they work… But, I am curious. Perhaps they will come up with different solutions over time and the tool itself will remain consistent.

  • David Farber

    Works fine on non-sidewall? Main tread area works too?

  • I am not sure, to be honest. We used it on a Maxxis Rekon (120 TPI) and Schwalbe Nobby Nic (29×2.6″ — not sure the TPI). I posed the question to Dynaplug and will let you know what I find out.

  • Mike Tatreau

    I’ve been seeing these online for the past few months, and I’ve been really curious about them. I love the concept, but I was afraid of the pointy tips. I’m glad to hear they’re not an issue. I might have to give it a try. How hard is it to get replacement plugs?

  • Not hard at all. I don’t think that these are available in many local bike shops yet, as far as I am aware. But if you click that Amazon link above, then add to cart, you’ll see you can add in 5 packs of replacement plugs for 9.99.

  • Yeah, two of the rips we plugged were in the main tread area…

  • Black Rainbow Project

    I use the Sahmurai S.W.O.R.D plug system. Having the driver and the plug insertion tool (pre loaded) in the ends of my bars is way more convenient to me. I can’t forget to bring them, and it means I just keep a strip of spare plugs in with my tools. I feel happier not having bits of brass hanging around inside my tyre.

  • Interesting; first I’ve heard of it…

  • Jon Schultz

    Genuine Innovations G2650 Tubeless Tire Repair Kit goes for less than $10, and comes with a mini insertion tool. I’ve used these a couple times and seem to work well. No fancy metal case though.

  • Yeah, that’s the one I was referring to in the first paragraph… I am not a huge fan; I got them to work, but they are a little frustrating, IMO. I know a couple people who are masters at them though. The Dynaplug is far easier with the preloaded plugs.

  • Mark Troup

    Not a ton of noise, couldn’t hear it at all at higher speeds. It was only when I slowed down that you could really hear it.

  • The Genuine Innovations kit is a solid piece of equipment for $8-10, and is definitely a lighter and smaller package. Considering that some larger cuts and punctures require multiple plugs I have started packing several packs of plugs on longer trips, ideally some smaller and some larger. I recently plugged a hole in Poland and within the next couple weeks was forced to insert another 6 or 7 plugs into the same, growing hole, along with several rounds of stitching to hold it all together. Not an ideal repair but I would plug the hole and it would hold for days and days, so I’d ignore it when in town with access to better tools such as a patch kit and a compressor.

  • Yeah, I’ve used that kit plenty of times and have regularly carried it for a while now. And, I get the $10 argument. But if one can it, I think the Dynaplug is far superior. Reasons are: 1. The Genuine Innovations plugs are not nearly as sticky and don’t bond to the tire as well. I’ve had many push out over time, so I started resorting to super glue to assist. The Dynaplugs are super sticky and even seem to expand to fill a bigger hole than the plug itself; 2. you have to dig the GI plugs out of whatever package they are in and deal with the fiddly [IMO] insertion tool… all of which is time consuming and this might be a factor for racers and such. As far as using multiple plugs, it works the same way, and while dynaplug only recommends 4 plugs at a time, I am guessing you could use more. Even so, I would likely stitch the tire prior to going any more than 4 plugs. In addition, you spend $55 on the made in the USA tool, then you can get more plugs for $10… and that price may go down over time if this becomes a widespread solution, which based on its increasing popularity in the western US, it probably will.

  • OK, here’s the answer I got: “The standard size bicycle repair plug can be used to repair all tubeless bicycle tires that are compatible with the size of the brass tip that anchors the cord in the puncture. The tip that will be inside of the tire is 7.7 mm long.” Note that there are also bullet tips that are a little smaller, I think…

  • So, I sent them a message and asked them. This was the reply I received: “Dynaplug repair plug tips are machined with tolerances tighter than .001″ which is needed for the repair plug assembly to work reliably. Dynaplug tested a variety of materials for the repair plug tips including plastic, but found that machining from brass was ideal. Brass is self-lubricating (ideal for inserting in rubber) and has a higher tensile strength than plastic. in addition, machining from metal fits with the Dynaplug priority to produce locally, quickly and cost-efficiently. Dynaplug machines both brass and aluminum repair tips in multiple styles using automated Swiss CNC machines running 24/7 at the Chico factory. Producing locally supports multiple styles and fast turnaround of 10,000 parts per day.”

    I’ve been carrying around the Dynaplug kit for a while, and have been pleased, so I splurged for their “racer” model a while back, mainly because it’s less fiddly, and I keep the old kit in the bottom of my pack with extra sealing thread. This last weekend someone at the trail head had a hole and their sealant had dried out – punched the small-headed sealing thread in there, and it sealed up even without the Stan’s doing its job.
    It’s also nice not to have to carry around little tubes of super-glue to get the threads to stick, like i used to with the Genuine Innovations kit.

  • anewprofile

    ive one for a couple of years
    its not light. its not light at all when you compare the alternatives. its expensive. and its not better than a 7USD equivalent on amazon. the razor and stuff are just gimmicks… use it twice and the blade is dull for example (besides being tiny)

    so, what are the advantages you may ask? well, it looks super cool, and fun to use. as a gadget, i like it.
    being pragmatic though, this is useless for bike packing. get the super cheap, super light, super reliable, super simple and regular tire plugs… that are sold everywhere instead… and if these dont work for you, you might want to learn how to use them (just like the dynaplug in fact, youll read a thousand reviews of people who dont know how to use it and cant seal anything).

    On these notes, I’ll just remember that this site is quite biased toward sponsors.

  • anewprofile

    its quite bulky and heavy

  • anewprofile

    when you have a thick kevlar reinforced tire casing of mtbs, the plastic is not sufficient.
    this is why regular tire plugs come with a metallic driver as well. on lighter tires i’d think plastic would mostly work, but thats not really a risk i’d take (having the bit break)

  • anewprofile

    i dont think the tip is supposed to fall off. seem like a potential issue. id remove the tire and get rid of it just in case. i had tires with the whole tip in the tire for a year in one of my tires, it never feel off. i use that bike 5 days a week for commuting

  • Black Rainbow Project

    … Until you need them! :)

  • I know how to use the $10 Genuine Innovations plugs as I have used them for years on plenty of trips across Africa, Asia, and tons of bikepacking trips here in the US. Dynaplug simply works better, IMO. If it didn’t I wouldn’t have written this piece.

    And your last comment is an unfounded attack; Dynaplug is not a sponsor.
