I am looking for a clear, understandable definition of long reach brake calipers. I need some kind of hint that will allow me to identify long from short quickly without mounting on a bike. Here is my issue, I have a bike that I am building up that I have what were called long reach calipers installed. With the pads in place they just barely reach the 700 rim and they are bottomed out on the arms. Perhaps the bike is meant for 27 rims and that is my problem. Any hints would be helpful.
Thanks
