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

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.

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!

looks great and lets see how they work

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

Great quality and came with different rubber inserts that you can choose from that fits best with the rims. Love the ability to use a 4mm Allen key to hold it in place while tightening.

Easy to install even for a first timer. Tight seal. Would get again

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

I love that you can choose your own seal and they come with a core remover cap. No issues going tubeless on my cheap giant wheels.

These valves not only look awesome but with the variety of seals I was able to get the perfect fit and a tight seal on the rim, must buy for anyone running tubeless setups

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.
