  • Familiarity: I've put it through the wringer

I'm just kidding, they are tubes. They hold air, and great if I you break your old tubes. If you have a 29in wheel and like a presta tube and need some extra tubes, grab these!

The tube you need!

  • Familiarity: I've used it several times

Even with tubeless tires I still ride with an extra tube. Gets you back to your car if you get a flat on the trail. This q-tubes presta valve tube does just that. Definitly worth strapping to your bike or carry in your pack.

There when you need them

    When you run tubeless you always will want a back up plan if you are to get stuck on the trail. They hold air and will work to get you off the mountain. Does the job.

    Glad To Have Them

    • Familiarity: I've put it through the wringer

    I hate using tubes, or needing them, but I'm glad to have them when I flat!

    Reliable and Affordable

    • Familiarity: I've used it several times

    Good Tube for the price. Picked up 3 or 4 of these so I never have an excuse to not fix a flat or take a ride. Running these on front and back and haven't had any issues yet

    They work

    • Familiarity: I've used it several times

    They hold air, aren't super heavy, and have a removable core. Work fine for the task!

    They Do What They Should

      You put them in your tire, pump em' up, ride to your hearts content. They do what they are meant to do.
      I keep and extra zip-tied to my bike in case of a flat. No problems with them.

      So much rubber!

        Gonna need a few of these if you like to ride your bike. Let's face it, you're going to get a flat eventually! Grab some of these and be prepared.

        Gets it done!

        • Familiarity: I've put it through the wringer

        This tube gets the job done for any flat that i come across on the trail. Unfortunately this did not come in a box and I had to use a few rubber-bands to conserve space in my pack.

        Its a Tube

          I think what makes a good tube is if you never have to think about it. This is a tube you never have to think about. It sits in your pack until you need it, and then it keeps air in your tire while you ride. It doesn't flat easy, etc. its a tube.

          Keep Rollin

          • Familiarity: I've used it several times

          Having a tube on hand is a small price to pay to keep you rollin if you flat on the trails.

          does the job

          • Familiarity: I've used it several times

          Keep one in my pack and one at home. Always be prepared.
          As the descrip says "Respectably light, durable, and affordable"

          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).

          GOAT IS GOOD

          Tubes .....

            What can ya say, they work great when your need them. Like the content states, these are light, durable, and affordable. What more do you want! Pull the trigger.

            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.
