    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

    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.

    Really like these valves. I especially like that they come with a variety of rubber washers for fitting the valves to different rims. Instead of cutting up old inner tubes to make washers you can just pick from the ones supplied with this product. Sturdy and no leaks. Nice!

    I really like these things. The stem cap with the core removal hole in it is a brilliant touch. Unneeded, but I still love it lol

    I tried fitting up my 27.5 MTB wheels using Stand tape and valves since theyre kinda the OG of the tubeless market. I could not get the stupid things to seal at all! Either tire just leaked and leaked from the valve stem - I went through 2 packs and not a single one would seal even with sealant! It would seal after a bit, but the second I touched it to even just check my air pressure, it sprung a leak again. I was just about ready to just give up on tubeless, but I figured what the heck, Ill try stripping the wheel down and rebuilding it with Muc Off rim tape and seals and OH MY HECKING GOODNESS!!!! The rim tape was much better than stans as well, but these valves are head and shoulders above the Stans valves! How these are better than Stans: - With these valves, you get all aluminum construction including a color matching cap as well as a back plate of aluminum that goes behind the inner seal. This allows the clamping force of the nut to simply squish on the seal rather than trying to pull the valve out of the seal (glaring at you Stans). - Another things these have is 3 different seal shapes that you can chose from to match your specific rim shape (Stans only has a small round seal thats not interchangeable or replaceable). I went with the rectangle(ish) one for my MTB rim. - These valves also have a small O-ring that goes in between the nut and the rim, which provides yet another sealing surface. Stans did not have this and this is where I would ALWAYS get leaks with Stans. I mounted both of my tires up (front and rear) with Muc Off rim tape and these valves and tried to inflate them. On my front, I didnt even need my air bomb to seat the tire! I needed it on the rear (or probably could have gotten it with another layer of rim tape, but whatever - no biggie). To my surprise, once seated, BOTH wheels hold air for several minutes with no significant drop in tire pressure even without sealant! Obviously, there are some little pinholes in there that will be sealed up properly once I put in my sealant, but the Stans setup was a fight just to inflate enough to set the bead! Needless to say, Stans is junk in my experience/opinion and I will be sticking with Muc Off from now on!

    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.

    Hands down, the worst bicycle related purchase Ive ever wasted money on. These valves are garbage! They clog if you look at them sideway and are completely overpriced. Spend half the money on Stans, WTB or some other reputable manufacturer on a better quality set of valves and ride with confidence that they wont leave you stuck on the side of the road trying to clear a clog so you can pump up your tire.

We know how frustrating it is to have a leaky bike valve that just doesn’t seal! So here at Muc-Off, we set about designing and making our own premium tubeless valves to solve the hassle of finding your tyre flat every time you go to ride. The Muc-Off Tubeless Valves are precision machined from 6061 grade aluminium, come in three different sizes and are compatible with most tubeless rim types with a Presta valve. We"ve covered all bases and designed our valves with a built-in valve core removal tool so that you"re never caught short. If that wasn"t enough, the Muc-Off Tubeless Valves are available in ten different eye-popping colours so that you can match your steed and customise to your heart"s content.
