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

Good value here imo. Purple matches my wifes bike so shes happy. No issues, just as good as the stans brand.

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!

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.

Im glad I purchased this item.

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.

A bit pricey for valve stems, but these are very high quality and look great.

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

Great service. Product just as advertised.

Very well made stems. Metal valve caps are nice.

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.
