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

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.

Just as described

I dont know if the quality has gone down on these or what. I bought this based on all the reviews. 2% with 1 star in 3K+ reviews. I bought the first set and it failed me the first time. Thankfully, I was pumping it dry and didnt waste any sealant. I wasted hours though trying to get my tires to seat and it turns out the valve core was not letting any air in. So, I got a replacement from Amazon thinking it was a rare occurrence. The second time around, both my tires are set. Sealant in and tubeless tires are a go. I thought that was that. ONLY for both valves to leak air out. Tried to pump air back and the valve core is just broken and we cant inflate the tires with the valve core in place. At this point, Im just going to try to replace the valve core rather than remove everything to return it. Im hoping it works, otherwise, i might just have to spend more money to have a bike shop fix it.

Very well made stems. Metal valve caps are nice.

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

These not only look great, but work FLAWLESSLY! I love how they have different rubber gaskets to fit different rims better. Super easy to set up and feel like really nice quality. Worth every penny.

Pretty cool

Really like these valves. I especially like that they come with a variety of rubber washers for fitting the valves to different rims. Instead of cutting up old inner tubes to make washers you can just pick from the ones supplied with this product. Sturdy and no leaks. Nice!

It was a bit more army green than lime green, the pictures don’t quite get that part correct. It was a gift though, and the receiver was still very happy with it.

I usually use 45mm stems for my wheels but needed 10mm more with these stems. This seems to be because that lock ring is thicker than the standard ring. I ended up needing the 60mm stems. The product seems pretty good and am only rating it a 4 because its about twice as expensive as it needs to be.
