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.

Used this valve when I converted my bike to tubeless and so far they have worked great! Love the custom colors and the built in core remover. Easy to install and good value.

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.

These stems are high quality. The caps replace the valve core tool you'd otherwise carry, which saves a little space in your tool kit. Cool feature.

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.

I installed these tubeless valves on my Evil Insurgent bike and there was no leak on the first try! Will probably order more for future bikes.

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!

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.

No need to pay for the over priced industry name brands. These work just was well at half the cost
