Muc-Off Tubeless Valve Stems

Dress up your wheels using these premium tubeless valves from Muc-Off. End the frustration of leaky tubeless valves that just won't seal. The Muc-off Tubeless Valve Stems solve the problem of finding your tire flat every time you get ready for a ride. These stems feature removable valve cores and 4mm Allen key slot for easy installation and removal.

These new "V2" valves are stronger and lighter, upgrading the aluminium grade from 6061 to 7075. Muc-Off have also made them even easier to use by introducing a new machined 6 slot channel in the base. These slots allow the tire to be inflated easier and can be used with most tubeless tire foam inserts.

Supplied with 3 sets of different shaped rubber inserts to fit a variety of rim shapes and create the perfect value to rim seal.

Features:

  • 7075 aluminum machined stems and caps
  • 4mm machined Allen key slot allows easy installation and removal
  • Valve core removal tool is integrated into the spare alloy cap
  • 3 rubber insert shapes to better fit various rim shapes
  • Each package comes with two valve stems, enough for two wheels

Oil slicks for the Grizl.
rating
by JasP

I purchased these valve stems to go with the oil slick water bottle holders I have on my Canyon Grizl. Not only do they look good but will work well with my tubeless tire system and the Cushcore inserts. With the extra ports Muc-Off makes it easier to add their NO Puncture Sealant without difficulty.

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.

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.

stem works and looks great as well. The cap is designed to remove valve cores but stripped on my first turn with the valve core being firmly seated in the stem I was using. I binned that cap and will probably never attempt to use the other cap to remove a valve core unless it is already loose.

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 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.

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.

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.

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!

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.
