These work well in Bontrager tubeless rims as well as a few other brands. They come with different rubber seats so you can get the best seal. The ability to tighten them with an Allen key is great and there's a flat spot on the nut that's on the rim side as well so it's easy to hold things still. Using on two sets of wheels at the moment and would recommend to others.
I use Stans on two of my bikes, and they work well. The second bike came with valve stems that were just a pain to set up. I ditched them, and used a set of Stan's that I had, and they worked great. They come in nice colors, as well, so you can add a little visual appeal to your ride. I know there are numerous other brands that would also work well, but I have had good luck with Stans so I'll keep using them.
I purchased these in colors to match my bikes. Not because I am vain, my bikes are. Disappointed at how quickly they gum up and muck up. They're supposed to be some kind of free flowing, two of the bikes I've installed them on have consistently stopped up. Rather disappointed. Looking good is only part of it. You expect it to work better
I got a red pair of these to go with a new bike for my wife. They look great! They do appear a little short on her overall Terra C wheels because the lock nut is a little larger than your standard nut. But they sure are a great way to add a little bling to your ride!
I switched to tubeless tires about nine months ago, when I upgraded the wheels on my bike. These stems work great and installing them was very easy. I've had absolutely no problems with them and they appear to be well made. It's also convenient to have one of the caps function as a value-stem removal tool.
Adding new or additional sealant is easy with these stems. Just take out the value stem using the valve cap that functions as a removal too. Then inject the desired amount or sealant, and re-install the stem. I use a Park Tool sealant injector for injecting the sealant.
If there's any downside to these stems, it's that they are a bit expensive.
Truth be told, I initially only bought these because they were purple and match the purple anodized bits I have on my bike. I was pleasantly surprised that these are actually some of the nicest valve stems I have ever used. They seal up nice, they don't seem to get as mucked up as some of the cheaper ones, and having the different rubber seals for different rim profiles is nice. I'll buy these again in the future...they are worth spending a few extra bucks on!
I started using tubeless road tires this year and I wanted a sharp looking stem for my hot wheels. My goal was to get a clean look on my Bontrager XXX 4's. I went with the 60mm in black, hoping they would not be too short. After experimenting with the different sets of grommets provided, I got the fit I wanted. I have enough length for inflating, and not too long so another squirrel tries to run through and take out the stem. A rubber o-ring, followed by the stylized cinch nut, polishes off the look outside. The core removal tool / stem cap works perfectly and can ride along if one chooses, at a slightly higher profile than the cap provided. Its the Swiss Army knife of valve stems.
Allowed a home install of tubeless set of tires. Came with three shapes of rubber rings for all rim types. The anodized color is a welcome sight on my black rims, and is kind of a flashy standout. The included core remover was not so effective, though.
I had the iredscent version. They worked fine and looked great. After 7 months, I had to remove the valve to replace a spoke. The portion you don't see that is in the hollow section of the carbon rim was so corroded, the threads were almost gone. The parts that you see still look great. In ride in Phoenix, AZ where there isn't a lot of moisture.
I didn't think "premium" valves would matter but these are a worthwhile upgrade. Haven't tested it yet but I think these will be less likely to clog ��other valves seem to have more rubber around the opening where the valve meets the rim, and these have more metal exposed. I've noticed on other valves that the sealant can harden around rubber bits.
I really like having all of the options for different profile rims. I ordered 2 sets, and needed a different profile for my 2 different wheel sets. They seem well made and have worked well so far after 2 months.
