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

Very high quality aluminum valve, nice to have a couple options for the inner rim seals, and a handy core remover built into the dust cap. Used these for my 1st tubeless setup on a road bike, and the seals here worked perfectly, got a nice blast of air into the tire with the core removed, just went very smooth, and they look great too!

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.

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

looks great and lets see how they work

Great tubeless presta valves.

The Best I have Seen or Used and they Look Great

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!

Very well made stems. Metal valve caps are nice.

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.
