BWSHLF Tubeless Presta Valve Stem 40/44/55/60/65/80/100 mm, Super Light Alloy Presta Valve Stem Kit with Valve Core Remover Tool and Valve Stem Caps - Multiple Color and Size Options(Pair)

Tiene buena calidad para el costo, totalmente funcional

The valve comes with two caps each. One cap is the regular cap and the other has the inbuilt valve core removing tool which works very well indeed. The only draw back to the valve is how much it sticks up on the inside of the rim. I couldn't slide the bead over it so I had to remove the tyre for the replacement process. It's installed now but I had to use the bike shop electric pump to reseat the tyre which wouldn't have been necessary if I could have just slid the bead over it.

I was a tad bit skeptical of these because I have never heard of the name before and chalked them up as cheap Chinese stems that would likely leak, but they had good reviews and the color I was after, so I decided to take the gamble. I am glad I did. They have a great finish to them, come in a very nice box, and work just as intended. These stems have everything you need to install them in your tubeless ready rim, are air tight and presented no leaks or failures, and have a high quality anodized finish that I have no doubt will last a while. There were easy to install, are very light weight, and the threads are smooth with no burs or difficulty screwing the nut retaining nut and o-ring on. The valve stem is removable for easy, mess free sealant injection. I would purchase these again if I had to and highly recommend them, especially if they have the color you are after.

Excellent

These allow a lot of air thru (similar to the cushcore) which makes it easy to seat the bead of mtb tyres using a floor pump (as long as it's a high volume low pressure floor pump designed for mtb's). These valves are a bargain so got a couple of them.
