Item # QTB0002


Q-tubes is the house brand of one of our favorite distributors, Quality Bicycle Parts. The tubes are high quality, produced by Kenda. They are black rubber with a 32mm Presta Valve. At ~182g/per, they're light, but not too light if you know what we're saying. While they state 26" x 1.9-2.125", plenty of us with 2.35 tires run them without a problem.

A price that can't be beat

  • Familiarity: I've put it through the wringer

For $5.00 a tube, you are unlikely to find a better tube. These tubes work well, are more durable than I initially expected, and work great with my 2.35" Maxis High Rollers. I haven't had any major issues with flats out of nowhere or strange leaks, thus I plan on buying many more of them in due time!

great tube at great price

  • Familiarity: I've put it through the wringer

Price certainly factors into a purchase of a tube, especially since it eventually is going to happen. We pop tubes, it's just the facts ma'am. For the price, you can't beat this tube. Very effective and is as durable as any other tube out there.

  • Familiarity: I've put it through the wringer

I ride hard. only use these tubes and continental tubes. run them in 2.35" maxis high rollers without any problems. 165lb rider, run ~35psi in my tires, these work perfectly.

Good Tube

  • Familiarity: I've used it several times

This is a great compromise of weight and durability as far as I can tell. I run tubeless and carry this tube as a back up, but have used them a few times and put quite a few miles on the one I used most recently and did not have any problems. Price isn't really a big factor in the tube game, but they do also keep the price pretty low which doesn't hurt.

Reliable tube

  • Gender: Male
  • Familiarity: I've put it through the wringer

Been using Q-Tubes for a few years now. Haven't had any issues with the stems leaking (normally the issue I have with economy priced tubes). I actually run these on my HT all the time that I just use on 10-15 mile weekend MTB rides, and can keep the pressure at 25-28psi -- no pinch flats yet.

  • Familiarity: I've used it several times

In the description is says people consistently run these tubes at 2.35. I've got them in my 2.4 Conti Mountain King Tires and have been running them over rooted and rocky trails without an issue.

Economy Commuter & Training Tubes

  • Familiarity: I've put it through the wringer

I use these daily in my commuter tires and after the goathead attacks each week, even with tuffy liners I can honestly justify just tossing them out after a couple of patches (must have been a bad week). They work well, hold patches well, and will get you from point A to B.

Solid tubes

  • Familiarity: I've put it through the wringer

These are my go-to tubes. The performance is really solid considering the low price point. Definitely recommend would recommend these and will continue to buy them

Good Tubes

Nothing fancy or over the top, but these are reliable mountain bike tubes with Presta valves at a good price. They work without issue with 2.25" tires despite the 1.9-2.145" rating.

Lasted Several Weeks

Wasn't the longest lasting tube but I was putting about 40+ miles on my bike a week, still wouldn't complain!

Great balance of Price and Quality

These are not the lightest tubes or built with cutting edge construction but they are reliable and priced right. I use these on my commuterized mountain bike. I always carry a spare and these tubes have never let me down.I have had much more expensive tubes give me trouble.

No brainer

Just basic tubes, nothing fancy. I like them because they aren't too bulky. They're so cheap, unless your looking for an ultralight XC tube, why buy anything else.

Good Standard Tube

I like to use these tubes, because they are a good price and they hold up great! No issues so far with these at all!
