Geometry on any frame is a sum of parts,but for a quick reference a shallow head angle will give a more neutral steer,seat angles will alter your position over the bb.There are several reasons you chose angles when designing or building a frame it can be fit,type of build (mudgaurd clearences etc )or intented use
Short stems and daft seat positions wont compensate for a badly designed or fitted frame
