I'm going to get a BG fit soon from a guy that does BG and has Serotta certifications. It's a place that is nearby that has good reviews. (Village Bikeshop in Grand Rapids).
I'm curious, what info should I get from them? Or rather, what should I expect? I just want to know because I plan on having him adjust my GT Series 3 road bike I have, but what if in a couple months I want to get a winter bike or something custom made by myself. I want info that will help me purchase the right size frame in the future too. Will they give you a stack and reach #? Or an optimal effective top tube length?
