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

These valves are super durable and very easy to install. Muc Off is quickly becoming one of my favorite brands in that all of their products seem to be very quality and hit that quality aesthetic feel that seems hard to find in the flood of cheap mountain bike products in the market. Highly recommend!

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

I have to admit these were a little pricier than I would have liked to have paid (not to mention that the valve core broke off inside the valve when I first aired it up... but it is possible that I was a little too forceful with the air chuck) but they add just the right amount of bling to my bike. Once I added sealant to my new Wheels with these valves there were no problems. They look great! They do exactly what they are supposed to do.

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!

Love these and the kit with all the different profiles of rubber seals for inside the rim. I myself am have the best luck overall with the ticker long cone shaped one . Seems to seal on any profile rim. It’s more about sealing up a hole and it’s shape vs the shape of the rim . The stems are phenomenal and the big rubber O ring in seal for the top cap are great for most rim profiles.

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

I love Muc-Off! However, this set came with a faulty valve core. After numerous attempts to seat my tire ( I wasted two Co2 cartridges, 3 ounces of sealant ) I realized the valve core was not allowing the air to enter the tire! Put in an old valve core and the tire pressured right up! This turned out to be a costly replacement for me.

Awesome valve stems, high quality and great looks. Worth every penny.

They look great, fit my hoops correctly and I love the different sized rubber seals that allow me to choose what works best with my rim. Shipping took a couple days to get started, but arrived quickly and safely thereafter.

A bit pricey for valve stems, but these are very high quality and look great.
