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

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.

looks great and lets see how they work

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!

Love these. Easy setup and great color match for my custom build. Definitely recommend.

My ENVE rims were continually losing air no matter how well I tried to seal the valves. These stems and grommets are the perfect shape and durometer to make a positive seal. They even came with rim stickers and a core tool. They are worth the money.

Easy to install even for a first timer. Tight seal. Would get again

Works great

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.

These are great tubeless valves. Anodized metal, and even the caps are metal. They even come with a valve core remover tool that you can use as a cap. Super cool. They include multiple rubber pieces for the inside the rims to seal it, so you can choose the one that fits your hoop best.

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.
