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)

Got these for my first time converting wheels to presta valves and tubeless.These install very easily, just thread the retainer nut on with the o-ring inside (watch for the o-ring being in that retainer nut, it could fall out perhaps).Snugged it all up, easy-peasy.I then put the sealant goop in the tire and mounted it up, sat the beads, then aired up the tires. There were no leaks from these stems, and still haven't been (I did this conversion in like late November?... don't recall). I occasionally check with soapy water spritz... no bubbles from the stems.Shout out to the sealant I used: Bontrager 'blue-sparkly' stuff... don't know what the actual product name is. I got it at a Trek store. It has done very well, haven't had to add any more (since Nov-ish time frame!), still all sealed up. When I say 'all sealed up', I mean from major leakage. Everyone tells me that their tubeless setups will leak down a smidge over a week, or if you burp a tire... so yeah, I run into that and since it's normal, I don't count it against the sealant. It takes a few top-off pumps once in a while. Worth it to get the better grip and lower weight of tubeless.I'm an XC rider, so no big sendy/jumpy stuff... so of course YMMV if you are all 'extreme' in your riding.I've been very happy with these stems though. When I've burped a tire riding and need to add air, the stems are easy to use and every time I've had to top-off a tire, zero fuss with the stems.

I had the easiest tubeless conversion ever and these aided in this. They seal up great and look really nice. They are light and the valve cores seem good so far. I'm super happy I bought these as they are like half the price of the muc off ones. The hex at the bottom of the valve really helps to tighten them down. These are great valves for the money

Perfect stem for tubeless riding. The cap is useful tool to remove stem.

These are very nice. I put a small square of Gorilla tape on the rim tape to provide a better surface to seal. Otherwise, the stem seal will slip beyond the rim tape and leak. Do not over-tighten the nut. Finger tight only.

Purchase when I converted to tubeless and wow, happy I went with these. They were easy to install, the perfect length and have been holding up for about a yr now. I've had no issue with leaks or them coming loose and was easy to inject sealant this way, highly recommended!

Good product but got the wrong color.

Solid product. Looks great. Reasonably priced. And the cap is also a tool to remove the core. What more do you want?

Upgraded valve stem on my Roscoe 8 with a new 2.8 tire. I love the multiple air holes in the bottom of this valve. Pair this valve with a new Maxis Recon, some Stan tire sealant and your ready for any type of ride

Compre estas válvulas por que en una rodada se "capó". Esats válvulas funcionaron de manera muy eficiente. Sellan bien y estan muy boniras, el color metálico luce mucho. Dependiendo de los colores de tu bicicleta, estas valvulas pueden ayudar a que luscan mejor.Los dos tipos de tapones que traen son muy practicos para proteger el alma y para removerla.Los recomiendo bastante!

Very good quality

Fin de buen material y te incluyen tapas de repuesto

Muy buen producto

Tuve que apretarlas muchísimo para que no fugaran
