Will Dynaplug Damage Your Carbon Rims?

- When I found out about Dynaplug, I had some concerns around whether it could damage carbon rims if the brass tip made contact with the wheel. I would love to take manufactures at their word that a thing is safe, thoroughly tested, and works the way it should, but all too often it just doesn't play out. So I figured it was worth buying one and testing what would happen if I forced contact between the brass tip and a carbon wheel.

This video came perfect, i just ordered my carbon wheels and researched about the dynaplug, thanks!
Great video mate , I was on the fence about ordering this item for my road bike .. I think it’s pretty safe to do so after watching this 👍
I haven't tested the Dynaplug yet but I do carry one just in case. With a couple layers of rim tape you get a bit more protection. As far as a permanent fix I have tested the Stan's Dart plug on one tire and it has held up over that past few months. Their plug is supposedly able to permanently bond to the tire.
I had the same concerns about these damaging rims or rim tape. So I'm surprised you didn't test it on tape. Appreciate the rough testing though, however the response you got has kinda put me off.
The Dynaplug support team refused to answer this very question, thanks for the video. I asked them what happens when this brass item is in the tire and it goes flat again and if it will contact the rim? Also, I asked what happens if the brass tip breaks off, do you then have this brass object rolling around in the tire? They also didn't seem to answer whether this was just a temp ride day-only fix. I've used bacon strips in the past and they were basically a semi-permanent solution. One other concern I had was that I use tire inserts as flat protection and if this brass tip is shoved into the tire will it be ripping up my tire inserts (which are essentially foam)?
I haven't found them to be very helpful, or professional (www.mamilian.bike/blog/2020/03/a-brand-ambassadorship-masterclass-dynaplug-edition).
I wouldn't use this a permanent fix. Like bacon, which I haven't had the best luck with, it can be permanent, but it seems a lot safer to remove it and patch the tire from the inside. I suspect that it would be fine with the insert, but it's impossible to say without testing it.
I have zero affiliation with Dynaplug but i have been using these plugs for over 5 years on road carbon wheels. I can tell you from my experience these are usually a permanent fix because the head keeps the tail from working its way out. I have had one or two that simply did not hold air well enough for whatever reason that required another remedy. Two or three times the tip has fallen off inside the tire - one of which was when I had to insert a second plug, it pushed the head off the first. In that case the tip did roll around and i heard it while going very slowly or when stopping. When moving it was pushed against the tire and I didn't hear it. When I got home, I removed one side of the tire and fished out the head and re-inflated. Repair held for the remaining life of the tire. To your other point, and the one that this video is testing, if I had a plug in my tire and hit a pot hole or burped and lost air and the tip hit the carbon rim, the head would likely deflect sideways since the tail is malleable - and it wouldn't hit head-on multiple times as tested. The tail is not supportive enough to keep it rock-solid and pointed at your rim. I've taken off plenty of tires with repairs and the head, inside the tire, can be moved around with your finger. If this was a pot hole, then one hit. If it was a burped/flat tire then I would likely stop as quickly as possible. I have had the original rim tape on my 5 year old wheels, which have seen a dozen dynaplugs and over 25 tires. They work very well.
Its a non issue due to the sidewall height
You’re overthinking it mate. Just plug it on an angle.👍
I'd rather "overthink" things in the shop then create expensive mistakes on the trail 😜.
Wouldn't the same thing apply to any metal tool used to insert plugs?
Potentially, but with the tool it's only there for a short period of time, and hopefully in a very surgical way. With the DynaPlug, you end up riding around with the pointy brass thing in the tire until you remove it. Either way, I think the results demonstrate that even if you made contact with the rim with a metal tool, it's unlikely to cause any damage.
i'd be interested how it would cope with a 90kg rider at speed with a second flat. Hand bashing in the test is probably only 5-10kg of force max
I'm 90kg and have been using these for years without issue...don't think about it and I'm regularly doing +60mph down descents. Getting a fesh flat with old plugs is a non-issue
play on 1.5 speed
You are trying to damage the rim with the plug still installed in the tool that gives you leverage and force. In much the same way an arrow head attached to the arrow would be easier to stick into an item than just the arrow head itself.
Yep, totally intentional (i.e. worst case). Although the plug would be fixed in the tire so it will have increased leverage as well.
Surely if your tyres are at such a low pressure, that the brass head hits the internal rim, you are likely trash your rims.
Riding on a totally flat tubeless tire won't trash the rim per se. If it stays on, it's a buffer between the road and the rim. Obviously, if you ride it long enough, or on a rough enough surface, there's only so much that the tire can do though.
Rider weight + high speed = more force on impact. Your "taps" are no where near the force of impact a rear tire might have hitting a solid piece of rock at high speeds. Just saying.
Dynoplugs have been around for years now and I never read any complaints so I'm sure they're fine
Thanks for your comment. The goal wasn't to mimic hitting a rock at high rotational speed. The outcome of that impact will depend greatly on the angle impact, shape of the rock, air pressure in the tire, the type of tire, and the amount of deflection encountered as the tire rotates. That is a very complicated thing to model whether there's a Dynaplug in the mix or not.
The goal here was to test whether the Dynaplug would damage the rim when making the kind of impacts one might expect after experiencing a second puncture, before noticing that the tire was flat, hence the "taps".
As an aside, it's important to keep in mind that since the rim and plug would be moving at approximately the same speed as they rotate, the velocity forces there should cancel each other out (i.e. if you toss a ball from one side of the car to the other while traveling 70mph, even though the ball is traveling at over 70mph it won't hit the other side of the car with the kind of force one might expect from a ball traveling 70+mph because the car is also moving at 70mph in roughly the same direction...). Which is way I did not address speed; it shouldn't matter.
@@Mamilian I think the title “Will Dynaplug Damage Your Carbon Rims?” needs a solid answer and not an answer to a very specific scenario. Not trying to be argumentative here so please don’t take offense. I’ve had several flats where the tire lost all it’s air before I stopped to notice. Sometimes, the tire is comprimised enough that the air escapes faster than the rider realizes. So is it safe under these conditions? It may be safe but no one is claiming to guarentee it. Rightfully so. However, like i mentioned in my reply I haven’t really read or heard anyone having their rim damaged while using one of these Dynaplugs. I’m not taking the chances and I’m glad Stanz came out with their Dart system. Much lighter, works as advertised and definitely safe for any rim :) Cheers!
@@liquidSpin IME, the flat-before-you-know-it scenario is very common (you seem to note the same thing), so that is the use case I was most worried about and set out to test. There are other scenarios, but many of them are difficult to test and/or difficult to isolate the Dynaplug's role in potential rim damage. I do think the "is it safe enough to use" question was answered (which was the goal). Definitely would have preferred wheel OEMs to take a stronger stance on the topic though. Unfortunately, very much a crapshoot on whether they would warranty a wheel if it was damage while using something like Dynaplug (probably safest to leave that part out :D).
You are correct, I could have been more specific in the title, but the Internet (and CZcams's algorithms) don't reward academic paper titles. There was a time when I tried to explicitly capture more of the nuance that exists in the world; it ended up being an audience limiter.
I was looking at Dynaplug for road use, couldn't justify the high price over standard rubber strips I use. From my POV, there is no difference over Dynaplug than other patching tools for tubeless, other than the high price. 💸
When you say "rubber strips" do you mean the "bacon" strips? If that is the case, I have tried those on road tires and it works until you use that section of the tire to stop, then the bacon gets ripped out... IMO both the Dynaplug and bacon stips are temporary solutions to avoid putting a tube in. Patching the tire from the inside and removing temporary item is the best long term option. Dynaplug is more expensive, no question, whether its cost is outweighed by the value is a personal equation for everyone. Personally, I bought it for racing, and there it totally makes sense, for me.
@@Mamilian im from Denmark so don't know the english word for it. But yes i think we both think the same with bacon strips. I only use them to get home, then I patch the tire with tubeless patches from the inside. What are you experience with tubeless tapes? My tape just blew a Hole through the small adjustment holes from my rims. Riding with pressures at 5.5 to 6 bars.
@@x03PSYKOBLONDIIE I've used a few different kinds of tape. Never had it break that way. How many layers were you using?
@@Mamilian i wrap it around once or twice around the rim.
@@x03PSYKOBLONDIIE It's my understanding that for road there should be 2-3 courses of tape (I do 3) to deal with the tight tolerances and higher air pressure. Given the issue you're experiencing I would try doing three, it probably varies a between tape. It's not a lot of weight for extra assurance.
I feel dumber after watching this video.
Try the dynaplug on your forehead!u
