I recently found a deal on some older model Hutchinson road tubeless tires and decided to give them a try. As I am riding Mavic Ksyriums, I didn't need rim strips to make the conversion to tubeless that most rims require so instead of buying a whole tubeless conversion kit (like Stan's) I just needed the valve stems. After I installed them, tightening the heck out of the nut, and mounted the tires (which was pretty darn tough), I coated both sides of the rim with soapy water and pumped like crazy with my floor pump. Within a few pumps, the tires sealed and I was able to pump them up to pressure like any tubed tire.I know the tire is the key to going tubeless, but you can't do it if you get air leaking around the valves and these have no such issue. It seems as if the tubeless tires hold their air between rides better than tubes do, so I know there is nothing leaking out from or around the valves.I am very happy with my tubeless setup and these valves are a vital part of the system that makes it possible.

I’ve used other valve stems, but THESE just make the job of setting up tubeless tires a little easier. Worth a few more bucks, in my opinion.

Used these when I went tubeless on my bike. I’d never done that before and as a newbie these were easy to understand and install. Gave me zero issues and are working as designed.

I changed my tubeless tires and thje presta valves were showing a little injury after two seasons of filling. I proactively decided to install new valves.The Campy two way wheels use a valve that has a rectangular rubber grommet on the inner part. It fits in the wheel without a problem.The Stanley valves are circular, and they don't fit. So, I took a blade and made the circle a rectangle. Now they fit.So,. good price, needed a knife to make them work.... only four stars.

I purchased these valve stems because of brand recognition. I am very happy with how this product has performed.

These seem tough and seal well for tubeless setups so far. Good length. I use with orange sealant.

I have put these into Shimao Ultegra 6800 tubeless wheels. Absolutely no problems so far (3 months of riding). They were easy to install and made it so much easier to fill the tubes with sealant. I can't even imagine why Shimano puts valve stems in these wheels without removable cores. Shimano leaves a lot to be desired in terms of efficient, logical design but as long as after market companies can solve their deficiencies things will work out.Great valve stems.
