I recently saw a bike frame on face book, that I really liked the looks of. Some people said the frame was a PG. Has anyone heard of these, or know where to find them? I appreciate any help you can give me.
The only thing I am aware of with respect to PG and bicycle frames is plain gauge. That refers to the type of frame tubing. Plain gauge tubes are the same wall thickness through the entire length of the tube. Higher end frames use "butted" tubes which means the wall thickness varies along the length of the tube. This reduces weight and alters the ride characteristics of the frame. The wall thickness is kept thicker towards the end of the tube to maintain strength.
