In fact anyone who knows anything about working on a bike knows how to measure chain wear with a ruler. If you truly live in a reality where you think chains don't stretch, and don't know how to quantify the stretch/wear you probably shouldn't be in an Internet forum giving advice on bike mechanics!
Technically they don't stretch, they elongate due to the pins and such wearing down creating more play in each link. Rubber bands stretch, metal chains elongate through wear. Call it stretch if you want, we all understand what that means here but don't go blasting other posters for using the correct term.
