Tubeless tires were supposed to mean the end of flats, but while flats are significantly reduced, they still remain a part of our life with tubeless setups. Stan's DART Tool aims to make the inevitable tear or large puncture quick to fix by plugging even large tears and holes with its barbed tip that anchors into the tire, and instantly reacts with latex sealant to form an instant, airtight seal. The barbed tip is designed to lock into place while riding, and pairs up with flexible material that conforms to punctures and bonds with sealant, wearing off clean, so you don't have to ride with scissors, or feel a bump in your tire with every rotation.

  • STAN's solution to tears and punctures on your tubeless setup
  • Barbed plastic tip anchors into tire, won't tear rim tape
  • Flexible material conforms to puncture and bonds with sealant
  • Excess material wears off clean so you don't need to trim
  • Lightweight and compact for easy storing in your pocket
  • Two pre-loaded DARTs included in clear cap to keep clean

Don't ride without it!

The DART tool has become an integral part of my daily riding toolkit. All you need is Stans sealant in your tires, a DART tool, and a pump to take care of pretty much any puncture/tear and keep rolling. I still carry CO2, a tube, and a tire boot, just in case, but I have not had to use any of those three since I got the DART tool. The presta core tool is helpful too, in case you want to quickly add an ounce or two of sealant - carrying a 2-ounce bottle of Stans sealant isn't a bad idea either! I just wish it was small enough to fit into the OneUp Components EDC tool without modification.

So Rare for Things to Work this Well

I've used it several times

It seems like it happens so often that I buy cycling stuff, only to be slightly disappointed in its performance. This is an exception. Thee things work like a dream. One little poke, turn the wheel downward, and what was a spewing volcano of sealant, hissing in your ear, becomes a silent new patch of tire. I absolutely love these things. Well worth the price.

Sealant dependent but fantastic!

I've used it several times

So I have had my personal set of these for a while but ordered two more with refill kits for friends as gifts. In my opinion, these are a must-have for any serious rider or racer that doesn't hate having rides ruined my flats. The sealant in your tire should be able to seal any hole that these are too small to fit but for any hole bigger, these come in clutch, even for big slices. In my experience, these perform the best with Stan's sealant and don't really work as well with completing sealant options such as Orange Seal. It's been pretty hit or miss for me with Orange Seal but worked perfectly with Stan's. I guess that makes sense as the feathers are designed to react with that sealant only. These are the only reason I am willing to ride lightweight XC tires all season long!

I've put it through the wringer

These work perfectly! No fumbling, super easy to use, and they work instantly and hold well. I've had a few in my rear tire for months now, and they are holding up super well. I would say the ONLY negative is the pricey refill plugs.

Spreading good karma

I've used it once or twice and have initial impressions
True to size

Long story short. If I see some one on the trail looking at their bike likes some thing is wrong I ask if they need help. Guy had a decent gash in his tire. I stabbed it with the dart and presto. G2g! I haven't even used it for myself yet but was so happy to see how well the product works. Worth the money. Got a refill kit on order too.


So quick and so easy

About halfway through a ~36 mile ride we had a flat. About a 1/2 in slice in the tire, oh no! But wait! I remembered I had my Stans Dart. Pulled it out, stabbed it in. Bang! Hold on a tick, what is that sound? It is still not sealed! Twist it, flip it, jab the second one in! Blast it with some air, and we are on our way again. I cannot recommend The Dart any more. I will never ride tubeless without one again. No more sticky (or not so sticky) strips of bacon, no $65 dynaplug.

Works Great - Fast & Easy!

I've used it once or twice and have initial impressions

Works great. I got a puncture in my tubeless gravel tire and the sealant would not close the hole off as it was a bit too big. Stuck in this dart and it sealed up fine. I subsequently rode a few 30 - 50 miles rides before replacing the tire, so it sealed off nicely. I found this FAR easier to use than the bacon strip kinds of patch kits but YMMV. I would definitely recommend this.

Used mine for the first time yesterday

I've used it once or twice and have initial impressions

I used mine the first time for a partial side-knob tear on a Maxxis Aggressor. Once the Dart interacted with the tire sealant, the tire sealed up immediately and held solid for the rest of the day.

Couldn't get this to work

I've used it once or twice and have initial impressions

I got a puncture yesterday, and it sealed briefly, then kept reopening. Let my bike sit overnight and it didn't lose air, so I added a bit of sealant to replace what spewed out on me and my bike, reinflated my tire to 70 psi, and went for a ride. 10 miles in, it started gushing again, so I decided to finally try this out. Maybe the puncture was too small? Maybe I didn't use the tool correctly, (although it seems pretty straightforward), but I could not get the plug through the hole, and each of the darts broke at the tip. If anyone has any tips or advice, I would welcome the feedback, but as of now, I cannot recommend this product.


70psi! I'm wondering if this tool is better served on MTB tires with lower pressures.

The thing that jumps off the screen when I read your comment was that you're running 70psi. That's 3x the pressure that I run in my MTB tires, and I definitely think the results would be different (better) if the pressure was much lower. That being said, MTB tires also hold much more volume than a road bike tire, which translates to an overall more manageable situation if a leak is detected early. There are other "invasive" methods of fixing a puncture on a tire, and you might want to try one of those. The one that comes to mind is made by Innovations, called "side of bacon". It's basically a plug kit. I carry it with me in my saddle bag but I've never had to use it. It's small, super lightweight, and it's half the price of the Stan's plug kit. Good luck!

This is more directed at the two responses- Stans advertises the tool as MTB or Road worthy. Some tips I would suggest: Make sure you are putting the dart into the puncture in the direction of the puncture. Just because it's on the top of your tire doesn't mean it's straight. You may have to insert the dart at an angle. When you re-inflate your tire after using the dart, make sure it's at the bottom so all of the sealant in the tire gravitates towards the puncture/dart so that it seals. Also- did you use Co2 when you re-inflated your tire? If so, that could have degraded the quality of the sealant. Most sealant isn't meant to be used with Co2. Hopefully one or all of those help. I have the tool myself but haven't had to use it yet, luckily.

I had similar experience on road tires. The head broke and in one instance the shaft broke. I've spoken to Stan's via email and in a round-about-way they don't recommend this for small holes. When I explained I'm running 28mm road tubeless and (also) run them at 70psi, holes that seal at 50psi and open again when pumped higher, need to be addressed. I've resorted to using my tried and true Dynaplug for everything unless the hole is much larger -- then i'll use these things. I still cary both, but know your problem is not unique. Unfortunately.

I have had the same experience as you did, where the dart sorta folded sideways, with the plastic hole that the metal shaft is inserted into broke open. This was on a mountain bike tire (Maxxis Icon) with a smallish hole. Saying that the problem is that the hole is too small is not a great response since its big enough that you exceed what the sealant can handle by itself yet it’s not quite big enough to insert a dart into. I suppose you could use a reamer like what is included in some kits, like Dynaplug. I’d say that two out of six attempts/darts have failed so far. I’m much more careful now but it doesn’t take much for it to fail. At the rate of around five bucks a dart, that’s a lousy cost per successful plug.


Does the chemical bond work with Orange Seal or is this only compatible with Stans sealant?

Says “latex sealant” which is that bit Stans and Orange Seal are. Should be fine.
