Muc Off 1051 Black Tubeless Presta Valves, 44mm - Premium No Leak Bicycle Valves with Integrated Valve Core Removal Tool

Works great

Very high quality aluminum valve, nice to have a couple options for the inner rim seals, and a handy core remover built into the dust cap. Used these for my 1st tubeless setup on a road bike, and the seals here worked perfectly, got a nice blast of air into the tire with the core removed, just went very smooth, and they look great too!

Look no further, just buy it because you do need it and you’ve been putting it off and yes it’s worth the money!

Very well made stems. Metal valve caps are nice.

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!

So far so good

Muc off makes a great tubeless presta valve Pros Pack of two valves with replacement seals Comes with cap that can take off valve to fill your tire without taking the tire off Colors look great, easy to see the valve on your tire Tight seal, well constructed Cons: Price is slightly higher than most tubeless volves

Definitely a nice touch to your wheel. It comes with several different adapters for the inner rim and a stem remover. It served its purpose so I can’t complain.

They give you the adapters and settle in pretty quick. No issues for me.

Easy install, nice having options for the seal to make the best fit. I have a couple hard rides with new tires and these stems. Both working great and no leaks!
