Tubes: Gotta have em'

If you aren't running tubulars or tubeless, chances are you need new tubes on hand during a training ride. Stock up on the 700c x 18-23 Q-Tubes to keep in your seatpost pack or your commuting panniers so you can play 'Good Samaritan' on the bike path.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.

  • Butyl rubber
  • Presta valve

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)

Tube!

    This is a great value for a road bike tube. For the price it's easier having more around than it is to patch a flat.

    does the job

    • Familiarity: I've used it several times

    a tad heavy and bigger than my usual tubes, but $6 cheaper per tube for the 80mm stems that Im used to using. Life is always a trade off.

    Works real good

    • Familiarity: I've put it through the wringer

    Keeps air as a tube should. Havent had any defective valves that I've seen happen with some other brands. With the 80mm valve stem option, you can run them with deep dish wheels like Zipp 404s and not have to run annoying valve extenders.

    its a tube

    • Familiarity: I've put it through the wringer

    it actually works really well, very durable, ive been running these tubes for a few months now and have only had 1 flat, and finally deciding to get some extras.

    Cheap. Quality. Everyday tubes.

    • Familiarity: I've put it through the wringer

    I've been using these and purchasing them from backcountry for a couple years now. They roll easy and are quite durable. Only flats I've had have been from staples and nails, ZERO pinch flats! I also like that they always have 48, 60, and 80mm valve lengths available. Give them a try!

    Thanks for the review Sterling! Super helpful to get this feedback out to the community.

    i mean they're tubes

    • Familiarity: I've put it through the wringer

    They work. They hold air. They're not super light or super fuzzy or have glitter and sparkles. It's a simple item for a simple job. Chapeau for making something that works.
