Nowadays all bikes use what was once "Campagnolo-style" bosses for their shift levers. This was not always the case, however, and many companies had proprietary shift lever bosses.
Does anyone know more about this topic?
To be specific, I'm looking at a bike with "Shimano-style" downtube bosses. What's their compatability? The bike would probably get bar-end shifters instead, but then what's their compatability with cable stops?
Also, let's just talk about the subject in general, too. POST PICTURES OF YOUR DIFFERENT KINDS OF BOSSES EVERYONE! It'll be fun.
