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

Put them in your tire/fill them with air

  • Familiarity: I've put it through the wringer

These tubes perform exactly as they're intended. I've used a couple different brands of tubes and they're all pretty comparable for the most part, these are no exception. They hold air until you run over a goat head.

the standard

  • Familiarity: I've put it through the wringer

This tube won't change your life, but it will resist punctures decently, hold air, and come in at a reasonable price. I've experimented with light tubes and even latex tubes, but came back to these because they just work.

very durable

  • Familiarity: I've put it through the wringer

I put these on my fixed gear and am very happy with the results. these are very durable and resist pinch flats very well. I would recommend these to anyone.

Q-Tube'D

  • Familiarity: I've put it through the wringer

The Q-Tubes road bike tubes just work! The rubber resists punctures, and the valves don't leak. They're a durable and reliable inner tube at a great value. Highly recommended!

solid tubes!

  • Familiarity: I've put it through the wringer

Always have an extra pair in case the inevitable happens and i i get a flat. I can always count on these tubes to do the trick! Solid tubes rides well and last long!

Tube + Air + Tire = Go

  • Familiarity: I've put it through the wringer

Sweet tubes, not too expensive and so far no issues! Pretty much all I personally want from a tube!

Be Prepared

  • Familiarity: I've put it through the wringer

I keep around 3-5 of these at all times around the house for quick repairs. These aren't the lightest tubes so that's why I stash them at home and keep some lighter tubes in my saddle bag or jersey pocket when riding. It never hurts to be prepared so grab a few and you'll be glad you did.

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.

    Gearhead, Thanks for the additional info, re. the comparison to Conti tubes. I wish Conti still had a 48mm stem like the Q-tube offering.
