Muc Off 1051 Black Tubeless Presta Valves, 44mm - Premium No Leak Bicycle Valves with Integrated Valve Core Removal Tool

These are great tubeless valves. Anodized metal, and even the caps are metal. They even come with a valve core remover tool that you can use as a cap. Super cool. They include multiple rubber pieces for the inside the rims to seal it, so you can choose the one that fits your hoop best.

Looks great. Works great.

Im a man wholl gladly pay a premium for a product, as long as it solves my problem. My problem in this case was my very first successful tubeless tire installation. The wheels on my new Specialized Roubaix came tubeless ready and with valves that of course didnt work. They just wouldnt hold air around the seal. So I stumbled upon these, and since I would have them in my hands inside of 3 days, I bought them, despite how pricey they are. Now, once you see the package, you notice that these valves come with the tool for removing the valve core, which is a plus for me because I love new tools. They also came with 3 different types of valve seals for the hole where the valve pokes out of. All you have to do to swap them is remove the one that came installed from the factory by first removing the cap, lock ring, and the o-ring, which frees up the seal to be removed. Since my DT Swiss wheels wouldnt work with a cone shaped seal, I used the one thatll resemble Thors hammer when installed. You push that through the hole, make a good tight seal, and despite recommendations to the contrary in a video I watched, place the rubber o-ring over the valve, followed by the lock ring, which has room for the o-ring to make a nice tight seal. Finger tight only! Now, just complete the tubeless tire mounting as one would, seat the beads of the tires, and then add your sealant through the valve. I was expecting to have to do this whole process again, but lo and behold, the tires have held their seal. This is what I call PROBLEM SOLVED! No more leaks through the valves and I managed to actually seat the tires with just a floor pump. Ill update if I get any leaks or anything goes wrong, but I dont imagine anything going wrong. Expensive, YES, but totally worth it to let me get out there on my new tubeless tires!

Stems are well made and easy to install. They come with different size seals so they can be fitted to just about any rim type. They look great on the bike.

Love these. Easy setup and great color match for my custom build. Definitely recommend.

My ENVE rims were continually losing air no matter how well I tried to seal the valves. These stems and grommets are the perfect shape and durometer to make a positive seal. They even came with rim stickers and a core tool. They are worth the money.

I purchased these valve stems because of its reputation and brand name. I converted my Axis gravel bike tires to tubeless and have run into so many problems with these stems. The front wheel worked fine, the stem held up and didn’t cause any problems. The rear wheel was a pain I had to retape and try to install a the wheel three times. Each time it developed a small leak around the valve stem. I kept thinking it was a poor installation on my part, so I finally reached out to my LBS and had them install it for me. They told me that the valve was leaking and that they would need to replace it. They installed the Stan Valves. I wish I went ahead and bought the stans instead of picking Muc Off

Multiple seal options and very easy to tighten to rim. You can use your hand and a 4mm Allen key to get it as tight as desired. Would buy again and WAY better than Stan’s

Perfect, coming with multiple sets of rubber grommets is awesome. They look great as well, love the blue ✌️

These valves are more expensive than others but versatile. The optional attachments for various interior wheel shapes helps ensure you avoid air leaks.
