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 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.

These work great. Straight forward and look nice

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.

Valves work great! Was a little apprehensive to use them since I never installed a tubeless bike tire, but couldn’t have been easier. Like the fact that valve cover is used to remove the presta valve in order to add tire sealant.

It comes with built in valve stem remover which fits perfectly over the flats of the valve stem, so you can get it nice and tight...no leaks. The tapered rubber bottom seals into the rim nicely. I have only done the front so far but plan to do the rear soon. The color is nice matches other accessories. I have pretty deep rims and the length seems like overkill, but its better too long than too short. Whatever formula i used i could have probably went down by 10mm. Hopefully the O-rings last cuz they are super tiny, they probably should have packed 2 extra ones in the bag just in case. Will have to update review in a couple months after these have been put through more riding.

Worked out perfect and the packaging is awesome. Actually just ordered my second pair for another bike

My first thought when I saw the packaging they came in, was very fancy and good looking presta valves and caps. The packaging 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 end that sits inside the tubeless tires has several side holes to prevent sealant from clogging the inside ends of the valves and the hole in the center accommodates a metric allen wrench to properly seat the valve for proper sealing. Lastly, great price too.

Great steams. I really like the color and they work great.
