Item # QTB0006

One for the money, two for the show, three for the bike path.

The Q-Tubes Road Bike Tube isn't expensive but it is pretty necessary, so it's always a good idea to have two or three around, just in case. Keep 'em wherever, and rest assured that their durable design and reliable Presta valve will lock in the air, at least until you run over another broken bottle.

  • Butyl rubber
  • Presta valve

They Hold Air

  • Familiarity: I've put it through the wringer

Make sure to get the right valve stem length if you have deep section rims. They're perfectly suitable when you need a tube.

Eye Heart Q-Tubes

  • Familiarity: I've put it through the wringer

These are just an all around great tube. I trust them as primary, and as a backup. They aren't super light race tubes, but they also don't cost a lot. If you need tubes and want to save a few dollars while getting a solid product, Q Tubes are the way to go.

Great tubes

    These tubes did the job. Priced right. I bought 2. Fixed my flat and kept the other for the saddle bag. Only thing is I bought the tall valve stem by accident. I will definitely go with the short next time.

    This just in: Still a tube

    • Familiarity: I've put it through the wringer

    I use these tubes pretty regularly. That's not necessarily a good thing. If The price is "right", however I have noticed better puncture resistance and valve-to-tube seam reliability with the Continental Race tube and Race light tubes. I have started using the Q-Tubes as my spares and investing in higher quality units for primary duty.

    Home Replacement Tubes

    • Familiarity: I've put it through the wringer

    I keep a slew of these tubes at home- they do the job and i'm always ready for the next ill prepared friend to stop by wanting their flat fixed.

    Great tubes for the money

    • Familiarity: I've put it through the wringer

    Q Tubes are a great tube for the money. Stock up and be ready to rock when needed.

    Q-Tubes Road Bike Tube

    • Familiarity: I've put it through the wringer

    nothing negative to said perfect for the price it holds air doesn't leak air, better than patching the old tubes

    Good tubes

    • Familiarity: I've used it several times

    Not a whole lot to say about these, they seem to be durable and hold air well. No flats yet about a month in riding some fairly rough roads. 60mm valve stem clears my super hip 42mm rims well allowing easy inflation without being overly long.

    They're Tubes, and they Hold Air.

    • Familiarity: I've put it through the wringer

    I want to try and answer some questions that people may have about these:

    "Do they hold air?" Yes
    "Are they bike tubes?" Yes
    "Are they really that cheap?" Yes
    "Do they work?" Yes

    They are tubes. Get like 4 of them at a time, and you will be set for the year.

    Trouble will find me.

    • Familiarity: I've put it through the wringer

    I lost a side wall to a round-ass rock the other day. It wasn't sharp, nor was it particularly large. It was just slightly larger than gravel with apparent litho-super powers.

    Fortunately, these tubes are affordable enough that losing one to a brush with a very harmless-looking rock isn't too big of a hit, economically.

    Best bang for your buck

    • Familiarity: I've put it through the wringer

    Removable valve cores for your sealant, durable rubber, various lengths of valves for all rim types...sounds like a winner.

    Doesn't Get Any Better

    • Familiarity: I've put it through the wringer

    I love these tubes, that being said i don't really know much different, have used them for a while and they are awesome. Repairing them is easy and continues to allow a good life span even after repair. Don't hesitate

    Great Tube, Removable Core

    • Familiarity: I've put it through the wringer

    There's a common mis-belief in the industry that all tubes are made in the same factory (like a auto oil filter)...I would disagree. From my experience the Q-Tubes tend to last longer than many others that I have used, maybe a little thicker maybe dumb luck but I'm going to stick with them. The removable valve core is a huge advantage as it allows for a sealant to be put in, which if you ride at all you hate getting flats so a little sealant never hurt. The other great advantage is the possibility to use a good valve extender. There are 2 types of valve extenders 1 that simply goes on the existing valve and is a hollow tube (opinion these kind suck as there are potential problems like the valve closing and air loss when filling the tube with air); 2 a version where the valve is removed from the tube, replaced by the extender and valve re-installed on the extender (these kind kick a$$ and are the way to go)
