I did a Google search, but couldn't find the answer to this: Is there a quick (visual) way to determine if a brake lever (mountain bike lever) is for old-style cantilevers or for "V" brakes? This is, of course, assuming that the lever isn't marked "direct pull" or anything. Trying to determine if I can use what's in my junk box or if I'll have to buy a new set of levers.
