Trustworthy

  • Familiarity: I've put it through the wringer

These Q-Tubes have been awesome. Affordable, yet hold up just as good, or even better than other inner tube brands I've tried. Plenty of tire and valve stem sizes available which makes it easy to find the perfect tube for your wheelset.

Serviceable Tubes so far.

  • Familiarity: I've used it several times

There's really not much to talk about with these inner tubes, which is a good thing. They're cheap and effective so far. No punctures caused by road debris or other riding-related events through 150 miles. Also, no significant air loss over time as far as I can tell.

The option of variable stem length doesn't directly impact me but I can see how that'd be a nice consideration for people running deep sectioned wheels.

Holds Air, and fits in tire.

  • Familiarity: I've put it through the wringer

These do their job. They hold air and you can use them for your bike. That is a double win!

Reliable tubes

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

These are quality tubes. It’s great that they have options of different valve lengths.

Quality

  • Familiarity: I've put it through the wringer

What you would expect from a bike tube. Just make sure to specify the correct valve stem length pending on how deep your wheels are

Reliable

  • Familiarity: I've put it through the wringer

Been using these for years and never have had an issue. Great value! Stock up.

Great spare

  • Familiarity: I've put it through the wringer

Q-tubes makes a great spare tube for keeping in the saddle bag. I appreciate that I can get very long valve stems (up to 80mm) out of the box so I don’t need valve extenders even with deep dish rims (and nothing is worse than finding out that your spare tube won’t work b/c of a short valve stem). I’ve found them to be quite durable and effective.

Value...

  • Familiarity: I've put it through the wringer

...with this tube. Inexpensive and does the job. Put a little sealant in them and they last forever. Great training tube!

Keep It Simple

  • Familiarity: I've used it several times

They're tubes, they hold air, what more can I say. They've held up to biking to the bar, riding local paved trailways and the periodic gravel run. Valve stems seem to be sturdy and high quality as well. We'll see how long they last. So far, so good.

I know what you're thinking..

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

..its a tube. And you're right. But for the price and quality I have no complaints, and that's where the bar is set.

Always need some

  • Familiarity: I've used it several times

I always have about 6 of these on hand because things happen. A great tube for the money, never had any issues with them.

Q-Tubes

  • Familiarity: I've put it through the wringer

As everyone else stated - they do their job. I've been buying Q-tubes for YEARS and have never had a single issue.
