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

Backup to Tubeless

  • Familiarity: I've used it several times

I don't normally run tubes in my tires unless my tubeless setup fails and a tube is required to make it home. The few times that I have used these tubes they have worked great.

Get's it done

  • Familiarity: I've used it several times

Nothing fancy here - these tubes just work. Removable valve core means I can put a little sealant in the tubes, which really helps fight the goat heads we get at certain times of the year here in Utah. Price is right.

Good Price Okay Tubes

  • Familiarity: I've used it several times

I had to replace both innertubes in my commuter bikes and chose these because of the price. Unfortunately, I got a flat tire on my first day riding with these. I won't blame it completely on the tube because the route I take is pretty rough and I get flats often on it. At the same time though I wish that these were a little bit stronger.

Great.

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

Bought these for spare flat fixes and thankfully, they've sat idle in the saddle bag. I'll report back if I ever have to get around to using them.

Removable Valve Cores

  • Familiarity: I've put it through the wringer

I buy these tubes specifically for the removable valve core. That way you can fill with your sealant of choice and avoid all the goat heads.

Industry Standard

  • Familiarity: I've put it through the wringer

The only thing worse than having to buy tubes in 2018 is buying tubes that aren't 'Q' tubes, just don't do it! With soo many road tires going bigger and bigger and grinding gravel on eveyone's mind, it is time to make sure your old spare is up to the task of keeping you out riding and not just a band-aid to get you home.

When you can't ride tubeless, you might as well run a 'Q' tube!

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!

    I love bikes

    • Familiarity: I've used it several times

    And bikes need tubes... This one works great.

    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.

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