This tube is mated to Micheline Protek Urban 700c-35 and has not had a flat since installation 500 miles ago.
loses only 2-3 psi per day at 70 psi.
I had four flats within two weeks against the inside of the rim with brand K. I ordered a couple of these Continental Tours and a couple of Michelin Airstops to see if it was the fault of my rimrim tape (I never could find any problem with the rim or tape) or if it was the fault of the tube. I put in the Continental and it has been over 30 days and 400 miles of riding and I haven't had a flat (so I haven't tried the Airstop yet). The overall quality of the butyl, the seams, and the valve look better than brand K also.
Just like they're supposed to.
Good tube for its value.
great everyday tube, reliable
I was impressed with the well built tube this is. will get this product again.
These were installed on my touring bike rebuild. I wanted durable, quality tubes at a reasonable price. They are holding up very well!
Have been using Continental tubes among others and these stand out - very little air loss over days, and reasonably light as well.
I changed all the tubes on my bike with these. No problems so far.
They do the trick. If you need some tubes, these certainly do hold air. Rubber side down!
New to the gravel bike so I have these in for a while to break in the new tires and then maybe go tubeless
This intertube has been working great so far, fit the rim perfectly. It seems like it is made out of high quality materials.
This is an inner tube, It holds air when not punctured. Not much else to say. Nothing really notable about this inner tube versus any other.
I like Continental products, never had an issue with them, these tubes pose as no exception.
I've used these Continental tubes with great success and will continue to use them.
I like the removable cores and have ridden the last pair 3 years without a flat.
Tubes are tubes, right?
Seriously, I like that these are a bit thicker. I don't race. I'm not concerned about weight. I just like to think I'm going to go out and ride and come back without flatting. If these contribute at all to my security, they're worth it.
Also, I'm a traditionalist. I like that Conti uses a steel stem with a securing nut. Classic!
Would recommend !
Good tubes hold air well just as a tube is supposed to. These are not the thicker style for puncture resistance but that not what you are paying for. These are a basic functional tube. Work well for what they are.
I'm used to tires losing 15-20psi from week to week, but these tubes hold the air and only drop 5-10psi.
I have Matrix rims and tires are hard to mount. I,wasn't offered a tube , say 25 to 32. The 3w to 47 were a,challenge abd ended up pinchibg one
