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

Sturdy materials. Well-machined threads. The inner gasket seated and sealed perfectly the first time, on both tires. The small o-ring makes the threaded nut stay tight.

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

Will never use any other valve stems. These are so worth the extra $. They install easy and seal first time, every time and you can use an allen key to tighten perfectly. Love the valve core removal tool built in to the cap. And love that they come with different shaped rubber seals so you can change them out depending on the shape of the inside rim.

Works great

So dope!! Fit well

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.

Easy installation with no leaks, looks amazing

Advertised as 6061 machined aluminum, but looks and feels like plastic. Did Muc-Off change something or have I receive a counterfeit?

Hands down, the worst bicycle related purchase Ive ever wasted money on. These valves are garbage! They clog if you look at them sideway and are completely overpriced. Spend half the money on Stans, WTB or some other reputable manufacturer on a better quality set of valves and ride with confidence that they wont leave you stuck on the side of the road trying to clear a clog so you can pump up your tire.
