When it comes to material quality, it will be good enough for mountain bikes if it is made for tubeless. In time you have a problem because it will slowly become a bigger and bigger surface where there is no glue anymore, and it will start leaking air. ![]() Because the sealant is liquid, it will dissolve the tape’s glue if there is any gap left. The second most important thing is how well it mixes with sealant. Some of these tend to leave a lot of air bubbles and gaps between the tape and the rim, which causes air leaks sooner or later. What is the most important about tubeless rim tape is that it’s sticky enough. So basically, the best tubeless rim tapes will be the ones that come in the middle of these weight-saving low-quality ones and the robust ones like Gorilla Tape. The problem with tubeless tapes on the market is usually the weight saving over quality the manufacturers prefer. I will try to explain and categorize rim tapes and rim strips to decide for yourself which are the best. However, it has some drawbacks like weight, and replacing the tape can be difficult because it’s so sticky. I find it the easiest to install properly, and it works amazingly well. I won’t give you a list of the best tubeless tapes, mainly because I always use two layers of Gorilla Tape. To understand the problems that occur with tubeless setups and prevent them, we must look at which tapes and tubeless valves work best and why. Not only that but if you get a puncture, the sealant will close the hole as it transforms into a rubber. If there are still any tiny gaps left, there is a sealant that you have to pour inside to seal those off. Tubeless ones hold air in the same way as a tube does, while the tire’s bead sticks to the rim and preferably to the rim tape as well to seal the system on that end. Normal tires have weak sidewalls, which often leak air unless paired with a tube. When it comes to the tire, it has to be tubeless-ready. It’s tensioned from the other side of the rim by a locknut, which you can usually see on tube valves as well. Those holes usually have sharp edges and are quite big, so the tape must be durable enough to last.Ī tubeless valve is a separate part with a sort of a rubber seal to close the valve hole on the rim and seal it completely. There needs to be a rim tape or a rim strip that will close the rim spoke holes to seal the air. The tubeless system doesn’t have a tube to hold the air but instead seals the whole space between the rim and tire to prevent air from getting out. But first, we should start by explaining how tubeless works in the first place for people who are new to this. Now that I’ve given you a short answer about tubeless valve leaking, it’s time to go into details. To prevent it from leaking, the tape needs to be checked and fixed if necessary, and the air gap around the valve needs to be sealed properly. The tape is damaged or improperly installed, or the tubeless valve is not sealing airtight. Tubeless valve stem leaking has two causes. That is why I’m writing this article to explain all the possible things that can cause this problem and fix it. And that is the problem because you end up removing and reinstalling the tire several times until you get it right.Īlthough, if you have some experience with tubeless valves leaking air, you can get it right the first time by taking all the precautions when installing tubeless on your wheels. However, you can only guess the problem unless you remove the tire and take a perfect look at it. Some people will say it’s easy they will claim that it’s something with the tape or the valve itself. One of those problems is the tubeless valve stem leak. Now, I can pretty much say what’s wrong with it in the first minute of looking at it, but some problems still require more work to figure out. Luckily, with experience comes a different approach and much better analysis. I could say it was for me as well for a very long time. Tubeless valve stem leaking air might be the most annoying thing to service for most folks. ![]()
