Sacrifice weight for durability.
Yes, these are heavy tubes, but I have only gotten one flat since I started using them, and no tube would have prevented that one. I've had them installed on a road bike with Continental Ultra Sport 700x28 tires for over a year, and have been through several sets of tires without having to replace the tubes. In my opinion, I'd rather ride with a little extra weight to allow more time in the saddle, and less time fixing flats.

PROS: Good Stem Length, Puncture Resistant

CONS: Heavy

Heavy but worth it
I just used these on the dirty kanza gravel grinder and never flatted. I had been running regular tubes (90 psi) and kept getting pinch flats on gravel but these have held up well so far. They are heavy though!

PROS: Puncture Resistant

CONS: Heavy

Heavy Duty!!!
I've got these on my cyclocross/commuter bicycle & I'd be amazed if I ever get a flat. These are really heavy duty tires that are thick & heavy rubber.

Not so thorn resistant
Then again, terrain I'm on is pretty much hell for a tire/tube. Went tubeless - much happier..

Do not buy!!!
The tubes didn't make it out of my house. I installed them during a full rebuild on a older cross bike hoping I could get some longevity out of the tubes. I was adjusting my brakes when one starting hissing. When I removed the tube the seem had busted. Luckily I had spare tubes.

CONS: Punctures Easily, Heavy
