Muc-Off
Tubeless Valve Stems

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!

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

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!

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.

Stock Roval valves leaked a bit. These are well machined and quality equipment and don't leak at all.

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!

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.

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.

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.

Easy to set up. Look great. Excellent value.

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

I had the iredscent version. They worked fine and looked great. After 7 months, I had to remove the valve to replace a spoke. The portion you don't see that is in the hollow section of the carbon rim was so corroded, the threads were almost gone. The parts that you see still look great. In ride in Phoenix, AZ where there isn't a lot of moisture.

it does the job with quality and style

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 install. No leaks. Great product.

I didn't think "premium" valves would matter but these are a worthwhile upgrade. Haven't tested it yet but I think these will be less likely to clog ��other valves seem to have more rubber around the opening where the valve meets the rim, and these have more metal exposed. I've noticed on other valves that the sealant can harden around rubber bits.

I really like having all of the options for different profile rims. I ordered 2 sets, and needed a different profile for my 2 different wheel sets. They seem well made and have worked well so far after 2 months.

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