I volunteer at a charity bike store. We collect donated bikes, all types and vintages, repair them and sell them. The procedes go to a charity program. Last year we sold 2k+ bikes. As you might quess, not all of the bikes can be fixed for sale. So these bike are stripped for usable parts. And since the people that are doing the stripping of the part are volunteers as well, they have different skill levels. Some don't know that there is a difference between v-brake levers and canti levers, they all go into the brake lever bin. So when I need a lever from the bin, I won't know which bike it came off of, or what kind of brakes the bike had.
My question is; How cna you reliably tell a no-name, unlabeled v-brake lever from an unlabeled canti brake lever?
We want these bike to be as safe as possible when we sell them.
