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)

I got the 55mm version for my 35mm deep wheels and it's a perfect fit. It looks clean and there's still plenty of room for my pump head to fit. These were easy to install and I got an air-tight seal without any issues. Just push down hard on the head inside the rim while screwing in the nut and there won't be any leakage at the valve. The caps look good and it's smart how they also function as a valve core remover. I gave one of them a try and it doesn't feel as good as using a proper tool, but it will definitely work in a pinch out on the road. These are well made and I'm happy with the purchase. If I buy a deeper set of wheels and need new valve stems, I'll come back and buy a longer set of these.

I love these. The attention to detail is amazing. First, the quality is good all around. The threads are precise and smooth. The grommet and O-ring are good quality with no abnormalities that affect usage. Top cap machining is excellent. While the basics of presta valve stems are the same and fit a standard, there are ways to stand out from the typical presta valve. 1) The O-ring is fully captured by the tightening nut. No matter how much you tighten, the 0ring will not push out or deform thanks to the deep capture channel of the nut. The last 4 photos illustrate how well the O-ring is captured. 2) The interior base is keyed for an allen wrench so you can hold the valve stem in place and torque your tightening screw down easily. See photo. 3) The interior grommet is flanked by a large base. Even if you torque the tightening screw down further than you should, it is hard for the gasket to go past the base. It is almost fool proof, although I still wouldn't torque this down to the maximum. You just want to remove any play in the stem when tightening. 4 )Both top caps serve as core removal tools. They fit well and make easy work of even the tightest cores. See cap photos. 5) The look is amazing. I use Bontrager tires & wheels so the B logo fits perfectly. These are great valve stems. The amazing grommet and O-ring design makes these a cut above the typical stems you see. Not too mention the top caps. While they still suffer from thin and weak shafts due to the presta standard, they are the same durable as any other valves regarding the shaft. Also, these valve stems will not fix a bad tape job. They may help gloss over a mediocre tape job at the valve hole, but a bad tape job will always leak. I 10 years of daily riding, I have tried it all, and these are my favorites thus far. Prestas are not perfect, but these help elevate the platform a bit.

second pair of these that I buy, because the first time was seamless. Second time was zero issues as well I clamped the valve just finger tight because I didn't want to damage my carbon rim, and that's all you need, sealant will take care of the rest. EASY set up and VERY cool valve covers, I recommend this

I used these in my Carbon hookless wheels which I run tubeless. I needed to replace one of my valves and took the opportunity to put on new tires, replace the rim tape and install these new 60mm presta valves. They have a nice design with nice size holes at the base which is inside the tire that helps prevent sealant getting jammed in and, if you are using a tire insert, it would work to let air with the insert blocking the airway. Installation was easy and the with only hand tightening, it sealed very well as the gasket gets compressed inside retainer nut. The two sets of stem caps, both with integrated tool to open the valve, is appreciated. Great value.

Nice quality and color for the price

Fits and works great

My first thought when I saw the packaging they came in, was they spared no expense in packaging to give you a first great impression, which the valve stems and caps appeared to also be of very good quality. The packaging and quality of the stems is what I would have expected from top shelf brand companies. The flats on the barrell nut made installing much easier and allowed me to snug the barrell nut by hand. The rubber o-ring fits in a recess on the barrell nut helping to further seal the tubeless setup. The anodizing looks great and adds some bling the wheels. The fat end of the stem that sits inside the tubeless tire has several inflation holes to prevent sealant from clogging the inside of the stem and the center hole accommodates a metric allen wrench to properly seat the valve for a confident leak free seal. You can’t beat the price too. I have a set on my full suspension and my fat bike.

Great looking and well priced. Nice function no issues what so ever. I bought the 80

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!

These Were A Bargain. Got A Few Sets For The MTB Rims.

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.

It is nice looking stems and perfectly fit into tubeless tire.
