Value Tube

  • Familiarity:I've put it through the wringer

Go to tube for the most bang for your buck. Always keep a stack of these on hand and few on bike.

GOAT IS GOOD

  • Familiarity:I've put it through the wringer

Price is right. Quality is very good. Just pay attention to the valve length you might need (deep v rims require longer valves)¦longer valves look silly but function fine on shallow wall rims).

    In the pack

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

    Keep this guy in the pack as a backup for my tubeless set up.

    Seems to be good quality but I haven't had to use it yet.

    as good as anything out there

    • Familiarity:I've put it through the wringer

    buy 3 or 4, they are solid and inexpensive and will save you on the trail.

    Great price for a tube

      Even though I run tubeless, it's a great price for a spare tube!

      Backup Tube

      • Familiarity:I've used it several times

      I always carry and spare tube even with a tubeless setup.

      Tube-surance

        I run Stan's No Tubes, so I really never have to rely on tubes; however, there is always that one time when a burp or large puncture can happen. You don't know when it'll strike, but when it does, you're gonna be walkin' far if you don't have any backup tubes. Keep a couple on ya, you never know when a buddy may need to use one.

        Tube

        • Familiarity:I've put it through the wringer

        They're tubes. I hope I never need them again as I'm switching to tubeless. But the large 29er size means a little extra rubber if I have to use them to tie something to my car. Tubes! Tubes.

        Tube

        • Familiarity:I've put it through the wringer

        It's a tube. It holds the proper air pressure and keeps you rolling and won't break the bank. Always good to have a spare, especially as a backup for your tubeless setup.

        doin it

        • Familiarity:I've put it through the wringer

        These things do what they do. Not too much to say other than they work.

        • Familiarity:I've used it several times

        Does what a tube should?holds air. And at least for the half dozen I ordered, has a removable valve core so I can load up Stan?s for some extra flat protection.

        Great Tube

        • Familiarity:I've used it several times

        As soon as I got these tubes had to use one. Was thankful I ordered a few in my last shipment. Great backup.

        Great backup

          I run tubeless on my ride but these are the tubes that I keep in my pack in case the worst happens. These are the tubes I trust to keep an epic ride from turning into a miserable walk.

          Good Value Tube

          • Familiarity:I've put it through the wringer

          I had an early season incident with my tubeless & have been running these in my procrastination to get them fixed. The tubes work fine but the stem is a bit short for my Enve wheels... 42mm+ stem works better - not a fault of the product.

          Great for running sealant

            These tubes have a removable core if you like to run sealant.

            Simple tubes, they hold air

              Not much to say about tubes, really, but these are pretty good ones. The removable valve cores are nice if you're running deep rims for 'cross, or if you want to shoot a little sealant into your tubes.
