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

Great service. Product just as advertised.

This is my second set of these. Bought my first set and enjoyed them so much I bought a man extra set. They are very well made and durable. They come with a valve core removal cap, and different print options depending on your rim.

The Best I have Seen or Used and they Look Great

Easy install, nice having options for the seal to make the best fit. I have a couple hard rides with new tires and these stems. Both working great and no leaks!

Im glad I purchased this item.

Awesome valve stems, high quality and great looks. Worth every penny.

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.

It was a bit more army green than lime green, the pictures don’t quite get that part correct. It was a gift though, and the receiver was still very happy with it.

I have to admit these were a little pricier than I would have liked to have paid (not to mention that the valve core broke off inside the valve when I first aired it up... but it is possible that I was a little too forceful with the air chuck) but they add just the right amount of bling to my bike. Once I added sealant to my new Wheels with these valves there were no problems. They look great! They do exactly what they are supposed to do.

Have used many tubeless valve stems from different manufacturers, so far these are hands down the best . There are two types of inner rubber mounts that make installation a breeze with any rim . Using these for a downhill application, and will definitely use these again
