Solid choice for going tubeless

Familiarity:

I've put it through the wringer

My rims came as tubeless ready. I used tubes for several years. Commuting ran through my tubes and I decided that tubeless would at least save me money on tubes. After some hiccups, I'm commuting 20 mi/day with no problems. These stems have worked seamlessly throughout the entire process. They are still going strong 6 months later with daily riding. 10/10 would eat here again

Not much more to add, just plain works, no problems so far.

The valve stems do the job they're supposed to...keeps the sealant in. Removable core makes refreshing Stan's sealant an easy job.

Is this bronze color?

Great Stem Wrong Color

Great stem that does the job and doesn't leak BUT don't buy this if you think you're getting a bronze stem that's pictured because you're not, there are only silver ones apparently. Backcountry photo studio needs to update the item picture.

Got a pair of these for my husband. This is his response: "Just converted my mountain bike to tubeless, and these valve stems do the job. Easy installation, removable core which allows me to add more sealant when necessary. Highly recommend."

They keep the air in and let you add it when you need to.

removable core

removable core is awesome for adding more sealant

I've bought a few sets of these now and have always had great luck with them. I always keep a spare set around as well. Inexpensive way to keep things easy when you're setting up new tires.

When dealing with tireless setups, these valve stems are the way to go. The round shape allows you to really jam them in the valve hole. I am always confident that these valves will hold up and I highly recommend them.

So it's 2018 and if you prefer to ride your bicycle on dirt or gravel, you should be riding without tubes. Once you have come to terms with that, you should get yourself two sets of these gems. One to aid in setting up your wheels and proper tires tubeless and one set for your tool box or to convince your riding buddy that they should go tubeless as well. Unlike some other silly shapes that other valve stems may have at the bottom, these circular ones work great with every rim that I have tried them on, and they do a damn fine job. There is a reason that people that don't run tubeless still know who Stan is, his stuff is class defining for sure!

These are super good quality and nice to have available in a pinch along with my spare brake pads and other random bits.

Simple, and awesome!

If you plan on doing downhill mountain biking you need to go tubeless and these are the best. Super easy to install at home and they work great. Pretty simple and not much else needed.

Breeze to install

I"m so stoked on these valves combined with the Stan's Injector. No more having to break the bead on your tire to reseal saves time and energy. I"m much more inclining to reseal more often now.

The best there is

These are by far the best tubeless stems out there. The conical shape and threads all the way down to the base of the stem even let you use these on single wall rims.

I installed these so I wont have to keep breaking the bead on my tires to add sealant. They were easy to install and don't leak. What else could I want?

Easy to use. They do what they're supposed to do. Stan's is a solid brand and make long lasting stuff. Don't forget your sealant when you're setting up your wheels.

No brainer for easy tubeless conversion

If you have a set of tubeless compatible wheels but haven't made the jump into a full tubeless set up, definitely go with Stan's tubeless valve stems. They are easy to install and last for most of forever. They are also affordable enough that its worth keeping a second set in your work bench at home.

they are super easy to use and work with about anything. long life span but I always keep an extra set around so I never have to worry.

Works great!

I used these to set up my Surly Rabbit Hole rims tubeless with Maxxis Chronicles. Both the tires and the rim are not technically tubeless compatible. Converted the rim with a layer of Gorilla tape. These work great even without a tubeless compatible rim if you are trying to do a ghetto conversion.
