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

The Best I have Seen or Used and they Look Great

Im a man wholl gladly pay a premium for a product, as long as it solves my problem. My problem in this case was my very first successful tubeless tire installation. The wheels on my new Specialized Roubaix came tubeless ready and with valves that of course didnt work. They just wouldnt hold air around the seal. So I stumbled upon these, and since I would have them in my hands inside of 3 days, I bought them, despite how pricey they are. Now, once you see the package, you notice that these valves come with the tool for removing the valve core, which is a plus for me because I love new tools. They also came with 3 different types of valve seals for the hole where the valve pokes out of. All you have to do to swap them is remove the one that came installed from the factory by first removing the cap, lock ring, and the o-ring, which frees up the seal to be removed. Since my DT Swiss wheels wouldnt work with a cone shaped seal, I used the one thatll resemble Thors hammer when installed. You push that through the hole, make a good tight seal, and despite recommendations to the contrary in a video I watched, place the rubber o-ring over the valve, followed by the lock ring, which has room for the o-ring to make a nice tight seal. Finger tight only! Now, just complete the tubeless tire mounting as one would, seat the beads of the tires, and then add your sealant through the valve. I was expecting to have to do this whole process again, but lo and behold, the tires have held their seal. This is what I call PROBLEM SOLVED! No more leaks through the valves and I managed to actually seat the tires with just a floor pump. Ill update if I get any leaks or anything goes wrong, but I dont imagine anything going wrong. Expensive, YES, but totally worth it to let me get out there on my new tubeless tires!

Great service. Product just as advertised.

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.

These valves are more expensive than others but versatile. The optional attachments for various interior wheel shapes helps ensure you avoid air leaks.

Hands down, the worst bicycle related purchase Ive ever wasted money on. These valves are garbage! They clog if you look at them sideway and are completely overpriced. Spend half the money on Stans, WTB or some other reputable manufacturer on a better quality set of valves and ride with confidence that they wont leave you stuck on the side of the road trying to clear a clog so you can pump up your tire.

Will never use any other valve stems. These are so worth the extra $. They install easy and seal first time, every time and you can use an allen key to tighten perfectly. Love the valve core removal tool built in to the cap. And love that they come with different shaped rubber seals so you can change them out depending on the shape of the inside rim.

Edited: well, this is slightly embarrassing. Originally reviewed these negatively because one valve wouldnt hold air even after reseating the valve/replacing the tape. I went back and looked at the tape again and realized there was some kind of defect in the entire roll and there was a faint score more that was leaking air into the spokes on one side. Replaced the tape with a fresh roll and the second valve worked perfectly. TL:DR theyre a little pricey but they fit snug and the colors are nice. Lean into your vanity and just get them, theyre only like $10 more than Stans.

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!

Have used many tubeless valve stems from different manufacturers, so far these are hands down the best . There are two types of inner rubber mounts that make installation a breeze with any rim . Using these for a downhill application, and will definitely use these again
