Description

Description

The "Q" in Q-Tubes is Quality Bicycle Products -- the 10,000lb wholesale behemoth of the bike biz. They're produced by Kenda for QBP so you know they're high quality and will work just fine in your bike. The presta valve stem is 48mm long and should allow easy inflation with most low profile semi-aero rims. And at 125 grams each, the Q-Tubes 700c x 30mm Cyclocross Tubes are still plenty light so as not to hamper your barrier bunny hopping ability.

  • 48mm valve stem
  • 28-32mm wide tires
  • Removable valve core

Work great as a spare

  • Familiarity: I've used it several times

These work great as a spare tube for a 29er. Lighter weight, but still blow up and support a 29er tire to get you back home.

Tube

    These are pretty solid tubes, they get the job done. They are heavier compared to other options out there but these are the best bang for your buck.

    Who uses these things?

    • Familiarity: I've put it through the wringer

    It's a tube. Let's get that straight.
    This is about as "normal" as tubes get. It's not a lightweight option, but that's ok. What it does have that will keep me coming back is a removable core. 'Nuff said.

    They are Tubes

    • Familiarity: I've put it through the wringer

    They're tubes, with removable valve cores, with fully threaded stems. Affordable and they get the job done!

    I hope it works?

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

    Haven't used them yet... keep them in my trunk-bag just in case!

    It's a tube

    • Familiarity: I've put it through the wringer

    It really does what all else tubes do which is hold air so you can ride your bike. May not be as light as other tubes but guess what? All tubes eventually get holes in them. Great thing about Q tubes is they do have removable valve cores which is an extra bonus

    Protection

    • Familiarity: I've used it several times

    Everyone needs a spare tube for when the flats happen... haven't used it yet, but hoping it works when I need it!

    No reason to get anything else

    • Familiarity: I've put it through the wringer

    Good tubes at a good price. Toss these in the saddle bag and you're good to go.

    Hold air well.

      Nothing bad to say about these tubes. I don't know what makes a tube great, but these have never let me down.

      Tubes

      • Familiarity: I've put it through the wringer

      Good tubes, no issues with dozens of purchases through the years.

      Basic tube... it works

      • Familiarity: I've put it through the wringer

      Use these tubes on a set of cross wheels for my boys bike, and they work out great. Nothing crazy or unique, but they do the job that is required of them.

      Holds Air

      • Familiarity: I've put it through the wringer

      These tubes do what they are supposed to, hold air. Medium weight so no to heavy but not super light. It is also nice that they have removable valve cores to make adding a little sealant a breeze.

      so far so good

      • Familiarity: I've used it several times

      no issues yet, seems as solid as anything I've ever used

      Nice Tubes

      • Familiarity: I've put it through the wringer

      They perform well and have a removable core so you can add sealant. What else can you ask for from a tube?

      Good tubes

      • Familiarity: I've put it through the wringer

      They do what they advertise. Hold air in a tube-shaped form. Get em
