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

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

My ENVE rims were continually losing air no matter how well I tried to seal the valves. These stems and grommets are the perfect shape and durometer to make a positive seal. They even came with rim stickers and a core tool. They are worth the money.

The Best I have Seen or Used and they Look Great

They look great, fit my hoops correctly and I love the different sized rubber seals that allow me to choose what works best with my rim. Shipping took a couple days to get started, but arrived quickly and safely thereafter.

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.

Muc off makes a great tubeless presta valve Pros Pack of two valves with replacement seals Comes with cap that can take off valve to fill your tire without taking the tire off Colors look great, easy to see the valve on your tire Tight seal, well constructed Cons: Price is slightly higher than most tubeless volves

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!

Im glad I purchased this item.

Easy installation with no leaks, looks amazing
