Muc-Off
Tubeless Valve Stems

Easy to install and the colors are great. No leaks using their o-rings and fit my new Zipp 303 Firecrest with no issues. Highly recommend.

After fighting with the stems that came with my Enve wheels, I got these and they work really well. Kept getting sealant leaking between the rim tape and valve stem, threw these in and problem solved

High quality valve stems that come with different fittings to fit your rims. By far the best looking valve stems available if that matters to you.

About the lightest and best sealing tubeless valves I've found, they work great on road wheels and gravel wheels. The big bonus is the valve cap is actually a valve removal tool which, actually works awesome.

Easy to set up. Look great. Excellent value.

The set works well. I have not had any air leaks. They are strong and they look good too.

These valves come with multiple grommets, to fit multiple rim shapes. Round grommets are not always the best choice. There is also a rubber o ring for the top of the rim.

These work well in Bontrager tubeless rims as well as a few other brands. They come with different rubber seats so you can get the best seal. The ability to tighten them with an Allen key is great and there's a flat spot on the nut that's on the rim side as well so it's easy to hold things still. Using on two sets of wheels at the moment and would recommend to others.

I purchased these in colors to match my bikes. Not because I am vain, my bikes are. Disappointed at how quickly they gum up and muck up. They're supposed to be some kind of free flowing, two of the bikes I've installed them on have consistently stopped up. Rather disappointed. Looking good is only part of it. You expect it to work better

I use Stans on two of my bikes, and they work well. The second bike came with valve stems that were just a pain to set up. I ditched them, and used a set of Stan's that I had, and they worked great. They come in nice colors, as well, so you can add a little visual appeal to your ride. I know there are numerous other brands that would also work well, but I have had good luck with Stans so I'll keep using them.

First time going tubless on road bike, in handling these you could see that they are well made, worked well, over 600 miles with no problems.

I got a red pair of these to go with a new bike for my wife. They look great! They do appear a little short on her overall Terra C wheels because the lock nut is a little larger than your standard nut. But they sure are a great way to add a little bling to your ride!

I switched to tubeless tires about nine months ago, when I upgraded the wheels on my bike. These stems work great and installing them was very easy. I've had absolutely no problems with them and they appear to be well made. It's also convenient to have one of the caps function as a value-stem removal tool.

Adding new or additional sealant is easy with these stems. Just take out the value stem using the valve cap that functions as a removal too. Then inject the desired amount or sealant, and re-install the stem. I use a Park Tool sealant injector for injecting the sealant.

If there's any downside to these stems, it's that they are a bit expensive.

Truth be told, I initially only bought these because they were purple and match the purple anodized bits I have on my bike. I was pleasantly surprised that these are actually some of the nicest valve stems I have ever used. They seal up nice, they don't seem to get as mucked up as some of the cheaper ones, and having the different rubber seals for different rim profiles is nice. I'll buy these again in the future...they are worth spending a few extra bucks on!

I started using tubeless road tires this year and I wanted a sharp looking stem for my hot wheels. My goal was to get a clean look on my Bontrager XXX 4's. I went with the 60mm in black, hoping they would not be too short. After experimenting with the different sets of grommets provided, I got the fit I wanted. I have enough length for inflating, and not too long so another squirrel tries to run through and take out the stem. A rubber o-ring, followed by the stylized cinch nut, polishes off the look outside. The core removal tool / stem cap works perfectly and can ride along if one chooses, at a slightly higher profile than the cap provided. Its the Swiss Army knife of valve stems.

Didn't need these at all but nice to add a little bling to my gravel rig. Especially appreciate the various fittings/grommets to get the proper seal to the rim bed.

Allowed a home install of tubeless set of tires. Came with three shapes of rubber rings for all rim types. The anodized color is a welcome sight on my black rims, and is kind of a flashy standout. The included core remover was not so effective, though.

Solid pieces of hardware. Super pleased with the quality and the fit in my Roval C38s. Better than the stock valves for sure. Muy bien Muc-Off!

Easily installed and filled with tire sealant. Worked perfectly and the color matched my prismatic color of my bike perfectly!!!!

Great product and I highly recommend
