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

  • Familiarity: I've used it several times

Everyone needs a spare tube for when the flats happen... haven't used it yet, but hoping it works when I need it!

No reason to get anything else

Good tubes at a good price. Toss these in the saddle bag and you're good to go.

Hold air well.

    Nothing bad to say about these tubes. I don't know what makes a tube great, but these have never let me down.

    Tubes

    • Familiarity: I've put it through the wringer

    Good tubes, no issues with dozens of purchases through the years.

    Basic tube... it works

    • Familiarity: I've put it through the wringer

    Use these tubes on a set of cross wheels for my boys bike, and they work out great. Nothing crazy or unique, but they do the job that is required of them.

    Holds Air

    • Familiarity: I've put it through the wringer

    These tubes do what they are supposed to, hold air. Medium weight so no to heavy but not super light. It is also nice that they have removable valve cores to make adding a little sealant a breeze.

    so far so good

    • Familiarity: I've used it several times

    no issues yet, seems as solid as anything I've ever used

    Nice Tubes

    • Familiarity: I've put it through the wringer

    They perform well and have a removable core so you can add sealant. What else can you ask for from a tube?

    Good tubes

    • Familiarity: I've put it through the wringer

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

    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.

    • Familiarity: I've used it several times

    Best tubes for the money. Would recommend.

    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.
