Review on 🔧 Schwalbe SV15 700C Inner Tube: Ensuring Optimum Performance and Quality by Phil Kuebler

A friend highly recommended Schwalbe whistles. Unfortunately, I didn't have the same experience as him. One of the hoses deflates when inflated. The other tube does not fit into the rim and does not fit between the tire and the rim edge. This is where the Presta valve is located. Simply put, the tube is too big for the inner diameter of the rim (although it fits my rim). I'm glad I noticed this as pinching would certainly have occurred. I've had better luck with cheap Wal-Mart whistles than with these supposedly better whistles. Sorry Schwalbe, you had two chances and you lost both times.
