it usually goes like...
"hey, would this xyz bso be good for me?"
~"idk, what is it going to be used for mainly?"
"umm, riding around"
~"if it fits you comfortably, it might be the one for you, potentially"
"idk if it'll fit comfortably... ???"
~"the lbs could help you with identifying what might fit you comfortably. They fit folks up often, so it should be pretty simple & quick for them to fit you up"
"oh, good call, I'll check the lbs out"
Chances are, that never happens. If it does, they tend to come out of the lbs with a suggested bicycle.
