Great.

Bought these for spare flat fixes and thankfully, they've sat idle in the saddle bag. I'll report back if I ever have to get around to using them.

- Familiarity: I've put it through the wringer
I buy these tubes specifically for the removable valve core. That way you can fill with your sealant of choice and avoid all the goat heads.

The only thing worse than having to buy tubes in 2018 is buying tubes that aren't 'Q' tubes, just don't do it! With soo many road tires going bigger and bigger and grinding gravel on eveyone's mind, it is time to make sure your old spare is up to the task of keeping you out riding and not just a band-aid to get you home.
When you can't ride tubeless, you might as well run a 'Q' tube!

These work great as a spare tube for a 29er. Lighter weight, but still blow up and support a 29er tire to get you back home.

These are pretty solid tubes, they get the job done. They are heavier compared to other options out there but these are the best bang for your buck.

It's a tube. Let's get that straight.
This is about as "normal" as tubes get. It's not a lightweight option, but that's ok. What it does have that will keep me coming back is a removable core. 'Nuff said.
DanielGearheadThey are Tubes
- Familiarity: I've put it through the wringer
They're tubes, with removable valve cores, with fully threaded stems. Affordable and they get the job done!

Haven't used them yet... keep them in my trunk-bag just in case!
KratzerEmployeeIt works
Thats all I care about.

And bikes need tubes... This one works great.
Andrew DickinsonIt's a tube

It really does what all else tubes do which is hold air so you can ride your bike. May not be as light as other tubes but guess what? All tubes eventually get holes in them. Great thing about Q tubes is they do have removable valve cores which is an extra bonus

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

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

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

They are black, you can put air in them, and you can go ride your bike. Whats not to love.
Scott GolsanBasic 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.
Greg E.EmployeeHolds 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.
James BleuerEmployeeso far so good
- Familiarity: I've used it several times
no issues yet, seems as solid as anything I've ever used
