So just new to tubeless , I had two moments of the stuff shooting out , one it sealed and one it won’t hold anymore than 30 psi so looks like the tyre is buggerd for tubeless (conti gp500tt)
This recent hole I would think should seal , it’s been topped up with 50 ml sealant a couple of weeks back so maybe it’s not the best sealant
Definitely the way to go, haven’t heard of this but have been using just normal sealant with TPU. The best bit is because there is no air leakage the sealant last a lot longer negating the ass ache of having to top up all the time like you do with normal tubeless. Plus you don’t have to deal with the tyres going flat regularly because tubeless are horrible at holding air.
My favorite so far for road riding has been Peatys. It’s the first sealant that managed to seal a literal slit in my tire. It’s also very stable with high pressure tires. For low pressure riding (MTB, gravel), I buy whatever is cheap at the time and all of the above have done just fine. Most sealants will struggle with road tire pressures
Edit: Large holes should be repaired by taking off the tire and installing a patch. I like the Rema Tip Top mushrooms. Not a fan of slim Jim’s as inserting the plugs can damage the rim or unbalance the wheel.
The combo tubeless/sealant has advantages but for me just too much hassle to deal with. My mindset is win or nothing so while sealant will probaly allow me to finish a race with a semi-flat, the time loss can’t be made up. Also the bike is a total mess with dried sealant all over it. And just don’t want to be bothered with changing the sealant every so often. Probably done over 100 events over the years and have only had three flats, fortunately none during 18 IM events. Non tubeless tires weigh less and I’ve just always had good luck with latex tube set up. Just my preference but to each their own.
I just started using the new Silca Ultimate, and to my knowledge haven’t had a puncture with it yet. So I can’t speak for how well it works. In the past I have used Muc-Off No Puncture, and Orange Seal. Both of those worked very well. I never had a puncture the Muc-Off couldn’t seal. But to be fair, I’ve never had anything that required more than a single dynaplug to help close it. The Orange Seal did fail on one occasion, but I found out it was my own fault for not maintaining the tire well enough. Aside from just refreshing sealant by adding an ounce or two in every few months, you need to fully dismount the tire and clean it up occasionally. I didn’t do this, and basically an Orange Seal snake skin formed around the inside of the tire, and it would filter out the latex, allowing nothing but pale orange water to get to the puncture, not sealing it (I was close to home though). I carry TPU tubes as a backup, but haven’t needed them yet. I think if you do it right, any of the major sealant brands will do the trick. And in the long run is a cheaper way to go. TPU tubes can be pricey. I used to race with latex tubes, and liked them as well, but would occasionally purchase bad batches of them that failed prematurely, and they can still pinch flat, though not as easily as butyl.
Yikes, my season long trial with Peatys was an unmitigated disaster. I could never get it to seal the bead effectively let alone even the smallest puncture.
I use TruckerCo Cream. I can’t remember getting a flat on the road with it but it saved me on my mountain bike a few times. Been using it on my road bike for a few years now. Honestly I’m terrible with maintenance and only top it off once a year before I go on vacation… pull the tire off, check tape, clean out the dried up latex boogers, remount, fill with sealant, done.
It’s a latex with some chunks of rubber in it that are supposed to help seal things up and it’s pretty reasonably priced.
I gotta say, threads like this, from pretty experienced folks that have been running tubeless for years, they are not super encouraging as an endorsement for tubeless. Seems like a lot of problems and hassle.
Sealant swap? Only when necessary, if the tires/wheels are used frequently and the sealant doesnt dry out….
When sealant works for small punctures, you dont know you have a flat until you finish your ride, and mabye see a bit of sealant on the back side of the seat tube. For larger punctures, a quick jab with a plug, quick fill with CO2, and you’re back riding.
When one flats on a tubed setup, you know it…and you’ve got to stop to manage it. While a very quick tube change can be 90”-120”, this could still be the same or longer than plug/gas/go. If one is not good at changing tubes… it’s A LOT longer. Have you ever tried to ride a tubeless tire and wheel with a tube in it instead of sealant? Good luck getting that tire off, tube changed, and tire back on in less than 2min.
Tubeless tires and sealant weigh nearly the same as tires/tubes, so there’s no significant difference in rotating weight (which does not matter in a tri/tt, once at speed).
Tubeless tires can be run at much lower pressures, which means more comfort.
Yes, spot on. Friends don’t let friends ride tubeless (on road bikes). Low pressures, yes tubeless is great. Under high pressure a lot of sealants are too fluid to plug the holes.
When my friends ask me if they should switch to tubeless, I ask them how often they wash their bikes as a sort of litmus test. Tubeless is a major maintenance item and I’ve found that the folks that do a yearly check up don’t want to put in the effort and then they do, they fail to maintain the system.
I’ve had many successful and clean tubeless installations. I’ve also had tires blow off the rim where the tubeless sealant atomized and coats literally everything.
Tubeless has to make sense where you ride. Before switching to tubeless, I would flat once per 1000km on the TT bike, which would result in me patching a tube and being on my way for a other 1000km. With tubeless, I haven’t had a single flat in roughly 3000km, but the tire I have on their now would weep and spew goop every ride all over my bike and kit. Now my expensive race suits have latex caked into them The New Peatys formula finally sealed the hole, but not before making a few suits look ugly.
There are pros and cons. I hate tubeless, but I’m a watt weenie and don’t want to give up the 1 watt in saved rolling resistance
I have used Muc-Off and Stan’s. I would have bought Silca’s, but at the time I thought their formula could not be injected through the valve stem. Now I know the can be.
Anyway, I have only had a couple flats total in the past 10 years. And those were slashes that no sealant could fix. More recently, I think I rolled through something small and sharp that may have micro-nicked my tire, because I have a couple spots that weeped a small amout of sealant and I lost no pressure. So, Stan’s gets credit for that one.
For a rider that is not riding weekly on glass and thorns and does not flat that often, do any of these make a material difference from one another?
