Its a tube!

  • Familiarity: I've put it through the wringer

Gonna need a few of these if you like to ride your bike. Let's face it, you're going to get a flat eventually! Grab some of these and be prepared.

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.

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.

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.
