I bought the red and color is accurate in the pictures. Easy installation. My only complaint and I have this issue with many of this stems, where does the o-ring go? On the outside or the inside? there seem to be differing opinions. and some valves don't even include an o-ring. So is it necessary? Where does it go? I put it on the outside, but it seems to me that it becomes too compressed. IDK. Overall, a good valve.
I went tubeless on my road bike about a year ago. While I love the comfort and reliability that tubeless offers, I have to say, I've had a hard time finding decent valve stems. These were the answer to my prayers. The pump I use (Joe Blow Sport) would constantly hang up on the tubeless valve stems when I inflated my tires. I would have to jiggle the head around after releasing the lock lever on the pump head to get the valve to release. This would eventually lead to the stem or the valve core leaking and/or breaking.
3.5 stars really...product worked as advertised, but checking air pressure before a ride top of valve broke off ruining my day. After looking at product they were built very thin walled. Part of the reason for breaking is how long they are also. Would recommend getting shorter ones or ones made out of stainless.
These work so much better than the original valves on my bike. They're so much easier to open and close. They seem to be holding air like they're supposed to. I love the stylish blue color because it matches my bike. I wish there was an option to buy more quantities at a lower price, and I don't need another core tool every time I buy a set.
The core was stuck on both valves. The white seal was torn and stayed in the stem. I had to use the old cores from my tubes. The tool that comes with these is good, but don't use it unless you have spare cores.
They hold air and are long enough for my roval wheelset. I bought orange and wish they had orange caps. They came with red for some reason.
Easy installation, works out of the box. No leaks at all.
Great quality. Seals well, and the valve stem remover is great.
