Muc-Off Tubeless Valve Stems

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.

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.

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.

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.

I have an orange bike with black rims with no lettering. Nice color offset and matches the bike.

Easy to install. No leaks. Great product.

Use these on some Aeolus 3 TLR rims. What can I say? They work. Durable, easy to use, don't get clogged with sealant.

As for valve stems go I love these not only for the colors but the valve cap as the a tool too and the different size rubber grommets it come with to get the perfect fit

The muc off team seems to have thought of everything here. Nice little upgrade to my tubeless setup.

They look good and they work well.

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.

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.

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.
