Item # SNT0007

Stan's No Tubes is all about eliminating the tubes in your tires, but you'll still need valve stems. That's why they make these Tubeless 44mm Valve Stems. They go in place of the valves that are integral with a tube, however they have a rubber cone built into the end opposite the valve to seat into the valve stem holes in your rims. Their universal shape allows them to effectively seal UST and Road Tubeless, as well as standard tube-type rims. Stan's No Tubes Tubeless 44mm Valve Stems have a removable valve core to facilitate easy sealant injection. This way you won't have to break the bead on your tires if you need to freshen up your sealant. They come in a package of two.

  • Tubeless 44-millimeter valve stems (pair included)
  • Removable valve core for sealant inject
  • Seals UST, Road Tubeless, and standard tube-type rims

  • Familiarity: I've used it several times

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."

removable core

    removable core is awesome for adding more sealant

    keep a spare

    • Familiarity: I've put it through the wringer

    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.

    Love these

    • Familiarity: I've put it through the wringer

    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.

    Tried & True

    • Familiarity: I've put it through the wringer

    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!

    Always keep a few in the toolbox

    • Familiarity: I've put it through the wringer

    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

      • Familiarity: I've put it through the wringer

      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

      • Familiarity: I've put it through the wringer

      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.

      Removable core stems

      • Familiarity: I've used it once or twice and have initial impressions

      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

      • Familiarity: I've put it through the wringer

      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

      • Familiarity: I've put it through the wringer

      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.

      easy breezy

      • Familiarity: I've put it through the wringer

      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!

      • Familiarity: I've put it through the wringer

      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.

      Go to!

      • Familiarity: I've put it through the wringer

      These are my go to valves for tubeless. Easy to install, seal up well, long enough at 44mm, and the valves are removable for added sealant if an injector is used.

      Buy 2!

        It never hurts to have extra valve stems in your tool box. You never know when or if you're going to need one. These stems are tried and true. Very durable.

        Still going strong

          These are the tried and true design that mount up to virtually any tubeless rim. They are a bit long for most alloy mountain wheels, but it you have a set of Enve's or Reynolds, the length is appreciated. Removable valve core is key for quick inflation with an air compressor. Brass seems to hold up well to multiple tire tire changes. Lock ring is adequate, but an extra o-ring would be nice to ensure a tight seal. That being said, I have never had problems if the wheel is taped properly.

          do you think this one works with crankbrothers iodine rims? thanks

          It works

          • Familiarity: I've used it once or twice and have initial impressions

          I put these on a pair of decade old rims. I did have an issue getting a good seal on one of them. Considering how beat up those rims are I'm surprised it worked out.

          Great Valve

          • Familiarity: I've put it through the wringer

          Not much more to say. Works just fine. Simple system, and Stan is the proprietor, so these tend to be the best tool for the job.
