Latex tubes are "tougher"

No flats this year as in none with 5,000+ miles using Challenge Parigi-Roubaix, Schwalbe One, Vittoria CX EVO III but mostly Compass Extra Leger tires.

Yes, they are more expensive, more difficult to mount, and you have to pump them up before every ride as if who doesn't pump their tires. A buytl tube is in my seat pack along with a patch kit just in case.

OP: when you get a flat, it is important to identify the reason otherwise you might get another flat a few miles down the road. Small sharp objects can partially lodge into the tire casing. These glass or thorns or small pieces of metal can usually be felt by running your finger along the inside of the casing or running a cotton ball inside. Then, pluck it out before putting another tube into play.
