When the tubes were advertised it was said they were great at holding air pressure for long periods of time. Well its true. I only air mine up every four to five days and could probably go longer if I wanted to push it. Well made product.
After doing some research on inner tubes, I found that this brand is known for its build quality. So far I am happy with the quality of the tubes and have confidence that they will be long lasting.
These tubes are so worth it. They are very high quality and you can see it when installing. I have never had the mysterious seam split or valve breakage like some other brands. There is just one small item after using dozens of these tubes. No, i am not fully on the tubeless bandwagon! About every fourth tube has a loose valve core. Not fully loose but enough to let the air out in about 1-2 days. A quarter turn of a valve core wrench fixes the problem, but it is annoying. I am learned to check the valve cores with each tube change.
I went from a regular valve to the Presta valve and overall the tubes have performed beautifully. They were easy to install and they have held air better than my last tubes.
Replaced a set of tubes when I put on new tires and am noticing that at pre-ride check, I have to top off with less air than the prior tubes. The valve feels very sturdy, too. So far, so good!
I purchased these Schwalbe tubes while on sale as they were less expensive than the brand of tubes I usually use for my road bikes. So far so good and don't have any issues to report.
