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

Easy to install, look great

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.

These are a bit pricey, but I had a hard time finding something in blue that seemed reputable, so decided it was worth it in the end. I bought them to replace the ones that came with my bike because they did not seal well when using the pressure gauge (and I wanted blue instead of black). These ones dont have that problem.

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!

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

I have had no issues or of these valve stems. Converted to tubeless with no issues or leaks of any kind around the stem or seal.

Perfect, coming with multiple sets of rubber grommets is awesome. They look great as well, love the blue ✌️

Very well made stems. Metal valve caps are nice.

Great service. Product just as advertised.

Installed these on my Blue Pivot Mach 429 Trail for a little detail. Nicely machined stems with machined caps as well. Extra rubber seals are provided too. Installation is a breeze if you know anything about wrenching on your own bike and tubeless wheel setup. Highly recommend.
