Description

The "Q" in Q-Tubes is Quality Bicycle Products -- the 10,000lb wholesale behemoth of the bike biz. 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. And at 125 grams each, the Q-Tubes 700c x 30mm Cyclocross Tubes are still plenty light so as not to hamper your barrier bunny hopping ability.

  • 48mm valve stem
  • 28-32mm wide tires
  • Removable valve core

Good tubes

  • Familiarity:I've put it through the wringer

They do what they advertise. Hold air in a tube-shaped form. Get em

They're tubes, they work...buy some

work as advertised

  • Familiarity:I've put it through the wringer

Great price and very functional. I use these for everything from road rides to gravel roads. If you are very critical of weight they might be a bit heavy but for me they work great.

Solid CX tube for the price

  • Familiarity:I've used it several times

I've rallied these out on dirt trails and on the roads with no issues. Can't beat having a few around in case you need them.

Good Value

  • Familiarity:I've put it through the wringer

If you're running cyclocross tires, you probably want to run them them tubeless. But accidents happen, and preparation is the key. These tubes are the ideal backup for that scenario, enabling you to get home in time for dinner. Worth noting these can also be used with the 40c WTB Nano TCS tires despite the 28-32 designation. Not the ideal long term setup, but again, they will get you home.

Great tube

  • Familiarity:I've put it through the wringer

Just what the doctor ordered. A great, all-around tube. Nothing more, nothing less.

nothing better

  • Familiarity:I've put it through the wringer

I think they hold up as well as anything out there, they are a tube after all. That being said you will go through some over the year so buy 5 or 6 of them and save yourself some hassle.

Removable Cores!

  • Familiarity:I've put it through the wringer

I always add a bit of sealant to help save my commute or those unexpected flats on a road ride. These are tubes and are great!

Do these have a removable valve stem? The picture seems to suggest they do, but there's nothing in the description about it.

A fine tube

  • Familiarity:I've used it several times

Put them on with some stubborn new tires but they seem fine. Plenty light and will probably hold up to potential thorns/glass, I'll know better in a few more miles.

Good Tubes Good Price

  • Familiarity:I've put it through the wringer

These tubes work well in both my 28mm road tires and 32mm cyclocross tires. Seem to be flat resistant enough, granted you don't pinch them while installing really stubborn tires.

Good for the price

  • Familiarity:I've used it several times

These tubes work well for the price, didn't flat anymore or less than other tubes I've purchased.

can these tubes work with a 700 c x 32 mm...

can these tubes work with a 700 c x 32 mm tire? The description says they are just for 700c x 30mm but usually there is a bit of a range to what sort of tire a tube can go in.

chrp604757,



I am using these tubes in 32's currently without any issues. The manufacturer lists the sizing from 28-32mm, but I think you would probably be safe using them in tires slightly beyond a 32.

Great tubes

  • Familiarity:I've put it through the wringer

After having three cross tubes from a local shop that all went flat in the same month, I moved to these and haven't had a flat since (also been about a month). Great tube for a good price!

What size range of tires do these tubes...

What size range of tires do these tubes fit?

Good tube.

    First tube change was a breeze. This is my goto tube for my cyclocross bike.

    Solid; removable valve core is nice

      The removable valve core you'll find on these is really handy if you're running deep wheels for 'cross, or if you just want to shoot a little sealant directly into the tube. They hold air, mate up to pumps nicely (no slipping off), and don't seem to flat any more or less than any other brand.

      Good Tubes

        I've had zero problems with these after a month of riding. Daily commutes to work on various terrain. You can't beat the price. Overall these are a good buy.
