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.

This is a really solid product, but no weight penalty. The raised air vent into the tire, prevents blockage by the sealant. The large and solid tightening screw on the valve, permits you to close the opening for the valve tightly and to reopen it easily; furthermore the sealant is kept away from the valve and it is nice and tidy. It all works much better than the original system that came with my expensive wheels.

I have purchased several BWSHLF valves in a variety of different colors. Why? One is they come in so many different anodized color options. Although these are basic black, sometimes you just need a bit of color on your bike. Two, the quality on these valves are outstanding. The anodizing doesn't fade, they are easy to install, they have fit on every rim I've ever put them on, and they just work great. And last, but certainly not least, they are an amazing value. These are literally half the price of the Muc Off valves and work just as well (yes, I've also used those!). I wouldn't be surprised if they are made in the same factory. Sure, the valves clog over time...but guess what? They ALL do. Even the ones that cost 2x the price. I buy a bulk pack of 20 presta valve cores for $8 and just replace them when they clog. I'll keep buying these tubeless valves and use the rest of the cash I save to buy a few beers.

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.

Very nice product worked exactly as it should. Definitely recommend.

These are solid tubeless stems. Have them to 1 year now and no problemsPros: Nice colorsEasy to installGood PriceEach stem comes with removal capsCons: None

Decided to put my inserts back in and give them a second chance (after nearly ripping a tire off in a g-out), but needed some new valves. These work great great! The silver goes super well with the other silver components on my bike. If you know your way around tubeless, these are easy-peasy. They have a built-in 4mm allen at the base and it makes install a breeze.

These valve stems look good, are lightweight and easy to install. I purchased the red 44mm and wish they were a tad longer. The color is great and they are noticeably lighter than the original ones. They came in a nice case and include two sets of caps, both can be used as valve core removers. My only concern is them holding up long term.
