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

Great Tube

  • Familiarity:I've put it through the wringer

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.

save some $

  • Familiarity:I've used it several times

$12 at the store, $9 here (on sale). not much else to it.

not bullet proof, and not made of paper thin rubber, so average flat protection.

my only gripe is that the 80mm stem is a full $2 more than the 60mm.

Value Tube

  • Familiarity:I've put it through the wringer

Go to tube for the most bang for your buck. Always keep a stack of these on hand and few on bike.

It's a tube!

  • Familiarity:I've put it through the wringer

They do the job of holding air admirably, and the valve core is removable if you want to use some sealant (handy when the goat's heads get bad here in Utah!)

Price is right and works great

  • Familiarity:I've put it through the wringer

Don't overpay for name brands.

Bulk order these...

  • Familiarity:I've put it through the wringer

I buy a ton every once in a while and never have issues. Fit is great, they hold pressure well, they are durable and inexpensive. I love when these go on sale and I can take home 20.

Basic Tube

  • Familiarity:I've put it through the wringer

Great basic tube. Nothing special here, but these get the job done.

Inexpensive spares

  • Familiarity:I've put it through the wringer

These tubes are good overall. They do what you'd expect them to do at a great price. Don't expect lightweight or puncture resistance though.

Stock up

  • Familiarity:I've put it through the wringer

Great quality tube without the hefty price tag. Pick the stem length of your choice, stock up, and go ride!

great quality tube

  • Familiarity:I've used it several times

These are great quality tubes for everyday dependable use. The 48mm valves are good for conventional and semi aero rim profiles, and the removable cores are great if you want to use sealant.

it's tubular!

  • Familiarity:I've put it through the wringer

Not the lightest tube you can buy but does a great job. Haven't had an issue where any other tube would not have had.

There are better options.....

  • 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.

So far, so good.

  • Familiarity:I've put it through the wringer

Has been tested through your typical road riding. No complaints as long as you aren't riding on the side of a mountain!

It works

  • Familiarity:I've put it through the wringer

This tube fills with air, and allows you to ride a bicycle when you otherwise wouldn't be able to without one. It will pop if you ride over a thorn or other sharp object, but otherwise, it will stay in tact for an indefinite amount of time!

55

No complaints

  • Familiarity:I've put it through the wringer

This tube has performed just as good as any other tube I have ever had, and these are inexpensive. There is not really much else to say.

55

Solid and cheap

  • Familiarity:I've put it through the wringer

I ride a good bit, and ride hard. In Utah we also have these horrific little guys called goat heads that are basically natures version of a caltrop. These work great for a cheap, functional, easy tube, and won't bankrupt you if you need to buy 10 to make it through the season.

55

as good as anything out there

  • Familiarity:I've put it through the wringer

play it safe and buy a bunch, the 80m will work great with mercury M5's, zipp 404, enve 4.5's, most deeper dish wheels without running an extender.

Cause flats just happen

  • Familiarity:I've put it through the wringer

Q tubes are my go-to. Bang for the buck is the best out there, removable valve core, and a durable as any tube around. If you're counting grams, I'd look at a race tube, but for day in day out use, these can't be beat.
