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

So far so good

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!

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.

I purchased these valve stems because of its reputation and brand name. I converted my Axis gravel bike tires to tubeless and have run into so many problems with these stems. The front wheel worked fine, the stem held up and didn’t cause any problems. The rear wheel was a pain I had to retape and try to install a the wheel three times. Each time it developed a small leak around the valve stem. I kept thinking it was a poor installation on my part, so I finally reached out to my LBS and had them install it for me. They told me that the valve was leaking and that they would need to replace it. They installed the Stan Valves. I wish I went ahead and bought the stans instead of picking Muc Off

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!

A very solid valve stem great color I got the gold one and it’s actually way better than expected in person will buy again!

Bought these to go tubeless on my TREK Rail 5. Sometimes I like a little bling, great choice of colors!

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.

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.
