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.

    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

    Tubular tube

    • Familiarity: I've used it several times

    Great tube. Holds up well and performs like it should. I use it as a backup on rides and it is light and smal enough to put in a small pack. Definitely would recommend it.


      I ride tubeless but always have some q-tubes handy. They do the job and are cheap enough to buy a few! Don't forget your tubes!

      So far so good

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

      Just starting using these and they have proven to be a great purchase. Reliable and get the job done.

      • Familiarity: I've put it through the wringer

      wish the stem was a little longer. Great tube for the price with a removable valve core!

      They work

      • Familiarity: I've put it through the wringer

      They hold air and keep a tire inflated, so they do the job. Nice plus is they have a removable core.

      q tubes stand by

      • Familiarity: I've put it through the wringer

      q tubes have been super consistent for me in road, cross and mtn. I always keep a stash on the shelf.

      Save Yourself From A Long Walk

        Most people are using a tubeless setup but it is still essential to carry a back up tube in your pack.

        Do yourself a favor a buy a few tubes to save yourself a long hike back to the car.

        You won't be dissapointed

        • Familiarity: I've put it through the wringer

        For my bikes that I still run tubes in these tubes are my default. I still much prefer running tubeless tires over anything with a tube but with proper tire pressure these tubes will hold up to mostly anything and are always nice to have as a backup.

        Also as some other commentators have mentioned, these tubes will fit in your friend's 26 or 29 wheel in a pinch if they forget to bring a spare tube.

        Gets 'er done

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

        It's exactly what you'd expect from a spare tube. Never travel without one because his little buddy will save your bacon when you send that rock garden a little too hard.

        Great Tubes

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

        Great Tubes for when you need to replace a tube, or in my case, get home after getting a flat on your tubeless setup.

        Get's the Job done

        • Familiarity: I've put it through the wringer

        Rarely have to use these things anymore, but good to know you've got a reliable tube on hand when you need it. I've used this brand on several occasions and they've gotten me home safe. Good price too.
