First Look: An Innovative Take on the Tire Plug, The Stan's Dart

Oct 7, 2019
by Daniel Sapp  

Ever since the wide acceptance of the tubeless tire, the conundrum has been "how to best fix a tubeless flat." Sure, there are a ton of advantages to riding tubeless but a hole in the tread of your tire or sidewall can quickly deflate the fun of a ride and render an $80 tire trash.

Sealants can do a good job closing up smaller punctures and tire plugs have become increasingly popular for larger wounds. Most tire plugs consist of a metal barb and a rubber strip designed to fill in and plug a hole or cut, similar to the plugs that have been used in car tires for years and while these work well in many situations but they do have their shortcomings.

Stan's NoTubes have long been a popular sealant and rim brand, They've decided to jump into the business of tire plugs with an innovative take on the tire plug for those larger holes that sealant won't seal by itself.

The Dart (Dual Action Repair for Tubeless) is designed to work as a plug in situations when sealant alone won't do the trick. It is unique in that it works in two different ways, mechanically - like a standard tire plug, and chemically.

Mechanically, it's a plastic barbed tip with a special material, developed by Stan's, that sits on a carbon post. The tip is pressed into the tire, as a plug, anchoring it into the tire. According to Stan's, the material is coated with a safe chemical that reacts with any latex sealant to further help seal the hole in the tire.
Stan's Dart Details
• Mechanical tire plug with sealant enhancing chemical
• Small size
• Two heads on tool
• Valve core remover
• Weight: 15 grams (complete tool, two Darts)
• Price: $25 USD, 5-pack of refills ($20 USD)
• Available: Late October
• More information:

The Dart's ability to react with the sealant, theoretically makes it more effective than a traditional tire plug, according to Stan's. The plug itself also avoids some of the shortcomings of traditional tire plug tools, mostly by avoiding sharp metal tips that can damage rim strips or users. The barbed tip of the Stan's Dart is designed to stay in place during riding and will not back out. Stan's claim that the Dart is best used on cuts 5mm and larger, with sealant typically sealing those smaller cuts.

The material of the plug on the Dart is laser cut, flexible, and more easily contours to the shapes of various punctures than a strip of rubber. It also has an increased surface area for the sealant to react with. The Dart material is supple enough that riders won't feel it when riding and it can even be used with road bike tires.

Using the Dart is a straightforward process. Riders simply press the Dart into a puncture, just as they would a standard plug, until the head of the Dart tool contacts the tire. The length of the carbon post that the barb sits on is the correct length so that when the tool bottoms out, the Dart is properly inserted to the proper depth. The head is dual-sided and can be flipped around so riders with larger cuts can quickly insert a second Dart.

The tool is compact and, at 15 grams, lightweight. The plastic body of the tool holds the dual-headed Dart apparatus and there are plastic covers that keep the pointed tips of the device safely covered.

So, does it work? Yes. I went through two packs of refills making various cuts in tires and was able to successfully seal most any puncture on the mountain bike tires I tested, minus the time I accidentally made a three-inch gash in the sidewall with a knife...whoops. The Dart is beyond simple to use and easy to throw in your pocket. Coming from having to separate rubber plugs that have melted together off a plastic backing, then attempting to get them through a tool, and finally finagling them into the tire on the side of the trail with sealant all over my hands and gear, the Dart is a HUGE upgrade.

Ease of use alone, the Dart outperforms any traditional tire plug tool. Reloading it is painless and the Darts do their job in sealing most punctures in mountain bike tires in my testing. I was surprised to see the Dart seal up several cuts I didn't expect it to, in tires with minimal sealant.

 I and many friends have had lots of success using pieces of an old cotton t shirt. Stuff it into the hole and then it sucks up the Stans sealant and creates permanent seal on the inside. Just trim the excess cotton on the outside with a knife and you are good to go. I have run months with multiple cotton plugs in my tire with no leaking issues. The cotton tshirt also costs next to nothing if you use an old one.

 On a Outback country ride we tied some dry field grass in knots and crammed it through a hole pull it back out tight against the tire. About a half an hour it held air and got us back to the car. It worked good for a organic free tire plug. I also believe my invention is way more environmentally friendly ;-)

+1 for the cotton t shirt patch. Sealed a 8mm slice once and the cotton went super hard inside and out. I struggled to remove it when i came to fix it several rides later. As its textured and soaks up sealant it doesn't slide out of big holes like worms do if the holes are big.

 I'm convinced that sealant does do shit other than spray profusely everwhere and create rotating mass in your tires. I have never, ever had luck getting anything to seal and I've used Orange Seal, Stans and Finish LIne. Orange Seal wouldn't even seal up a microscopic pin hole puncture in the center of my tread.

 Maybe its just me, but Ive had great luck with the Genuine Innovations Bacon strips, including similar sized holes in a sidewall. Just jam as many as you need into the hole, spin the tire to get some sealant on it, and reinflate with some CO2. Way cheaper too.

 Kuddos to Stans. The "worms" and their jenky installation tools just don"t cut it. I like and have been carrying/using Dynaplugs since they came out, but they don't work too well on sidewall punctures. This is next level stuff and could be useful on epics, enduros, and simply saving an otherwise nice tire.

 Agreed, looks cool. A better carry solution would be nice though. Make a version that fits in a handlebar, pedal spindle or steerer tube.

 Would this work with any other latex-based tire sealant? I get that you're trying to pair it with Stan's Sealant, but I am asking for those who don't run this particular sealant for any reasons.

 Anyone complaining about the cost. How much would you pay to A) NOT have to install a tube, B) NOT have to stop to pump up a tire with a slash that leaks even after using a couple a plugs. To me any improvement on what I already consider to be a pretty good system is welcome.

 I've already seen something very similar in trail (motor) bikes which are tubeless many many years ago. It's a good idea, but i guess that when you have to work on a completely flat tire with thin sidewalls it might be far less easy to use...
  • 6 1
 Ya the test he does isn't very realistic... Don't think I've ever had a flat where I've been off my bike, have the wheel off the bike and tool in hand. Usually only find out I have a flat after I eat shit into a corner... get up, dust myself off... think "wtf??"... pick up my bike, get on... then realize I have a flat. By that time the tire is usually completely flat. If I'm racing, I've already lost enough time that I'll just sit there and take the time to put a tube in. Or if I'm not racing, I have time to just sit there and throw a tube in... vs. trying to plug a totally flat tire that already had most of it's sealant shoot out.

At least when I get it home... I could probably save an expensive tire with something like this. Which would be worth the $25 entry price.

 @S851: I am using a "ghetto" one made from cork plug with the needle and prepared plug just fitted into there.

You get the Giant kit (which is like 150 CZK/ under 6 EUR) cut out the needle tool from the handle, put it into the cork plug, put there a coin into the cork to not push the needle thru on wrong end, glued a bit so it´s keeping in the place and voilà. It s maybe 20grams and its on the bike

 This looks pretty legit. As a long time advocate for large strip type tire plugs (not Dyna plugs) , this new techy design from Stans seems to have its merits. With that said, it still amazes me how many folks out on the trails still don't carry any type of plug.....
  • 2 0
 So, that plastic tip stays in the tire. In the off chance you get another puncture, and the tire deflates enough, would you run the risk of that plastic tip gouging your tubeless tape should you accidentally run over that tip on a flat tire?
  • 3 0
 Design of the applicator is way too big to fit into most peoples tool kits nicely... At least you could just buy the refill pack of plugs and improvise your own smaller applicator though, which is what I will do!
  • 3 0
 Cool idea, but the applicator looks much bigger than a dynaplug applicator and it doesn't look like it would fit in my current tool setup. Why is it so big?

 Really like the idea of the plug design but would've been nice of it was engineered to work with a standard plug insertion tool. I've currently got a plug reemer and inserter in my bar ends that I forget is there unless I need it and that plastic case/handle is a bit bigger than anything I really want to ride with.
  • 1 0
 Bought into the marketing on this, got burned. Didn't have luck with even one puncture. Often the holes were too small to jam the plug into. The plastic tip doesn't have the rigidity or strength to penetrate an undersized hole. No luck with large holes either. "the material is coated with a safe chemical that reacts with any latex sealant to further help seal the hole in the tire" BS. In all instances the puncture that was not solved with a dart, was fixed with a wormy sausage plug.

 Will the chemical reaction work with Orange Seal?

 At the end of one of those vids, he said if using CO2 to replace the air when you get home to preserve the sealant. I didn't know that was a thing - am I the only one?
  • 1 0
 sadly Stans doesn't always work with C02.
  • 3 0
 CO2 escapes more quickly from tires and tubes than air does and tends to dry sealants out more quickly. It's a good rule of thumb to always deflate and reinflate from a pump or compressor after using CO2 cartridges to fix a flat.
