Self-sealing bicycle tube hasn't been any more flat-free than standard tube.
Heavy, self-sealing tube seems like the answer to a flat-free ride, but my experience shows it about the same as a standard tube. I prefer Hardcase tires that already have flat-protection built in, and bought these self-sealing tubes to decrease the chance of getting a flat. The are very difficult to patch because the slime runs out of the whole and contaminates the area during patch preparation. The valve stem on one failed, so the tube became useless.
Pros You may be able to simple pump up the tire and continue your ride.
Cons Heavy, difficult to patch, slime sprays out of stem when attempting to re-inflate.
Bottom line I will NOT buy them again. They have TOO much slime in them and don't work as well as tubes I have manually added slime to.
I ride 700x23c at 110psi. The high psi may be a problem. On my folding bike with 65psi tires, the slimed tubes work great!
Thank you for your feedback.
