Hey all, I was recently involved in a traffic collision that totalled my bike, and I'm currently shopping for another frameset. I'm a little confused on stack/reach, having only mostly dealt with top tube length since previously I only rode more classic steel frames. I used a geometry calculator to establish stack and reach for my previous frame--a Lemond Zurich and have found that contrary to what I assumed I would fit (a size Medium with ~54cm top tube), the stack and reach seem to suggest that a size Small frame would better replicate my old fit. Does that seem right? My bike is in the shop at the moment being assessed for insurance, but I believe I am set up with a BB to Saddle measurement of 74cm, and Saddle to Bar drop of ~14cm.


Should I be aiming to replicate stack and reach exactly--or should I be doing something else?
