RSN Sports 2X Bike Tubeless Presta Valves Stem Aluminum Hi Flo 40mm Universal Red/Black

Mine is leaking, I used another from my previous setup which works fine. using this valve leaks and has caused me a headache to have to unmount mount my tire a few times debugging this issue.

Look great. My only complaint is that my stans seringe does not work on it the valve is too thin. Also if you try screwing on a mini pump it is really hard to get it work. I am switching back to stans. The pain is not worth saving $8

I got these for my new mountain bike (Framed Marquette Carbon) so I could set the tires up tubeless. These tubeless valves were easy to install. They also look great and match my frame color. Would recommend and would buy again!

Worked better than what came stock on my high end carbon wheelset. Since installing these, they have turned into an item I don’t have to really think about—which is a bonus for something as simple as valve cores. You could spend more... but why when these function just great.

I converted my bike to tubeless. Bontrager wheels. I used this valves and so far no problems at all. So I recommend them.

Fit perfect and good quality. No complaints so far and ive had them for some months now

One in my order had a faulty valve core so I had to use an old one I had laying around tostop a slow leak.I do not recommend these valves.

The valve stem is not threaded to the end so Many pumps will not work. I’ve ended up removing these and having to replace them with different valve stems. I recommend to go with something different than these.
