my current fixation / fascination in bike fit is the distance between knee at 3oclock and the elbows. look e.g., at lance pic on txdude pic post. some other folks also mentioned this distance. a lot of aggressive / good riders have almost no clearance here, some even practically have to squeeze their knees inside the elbows. playing with this idea i am trying a shorter stem. right now due to fairly good flexibility plus natural spine/hip configuration i have a good (i think) aero position with low front end and a flat rather than rounded back, but about 4-5'' clearance between knee at 3 and elbow. now perhaps this knee/elbow distance is a useless piece of info due to varying femur lengths, body proportions, flexibility limitations etc but my thought is that "scrunching up" the aero position & slightly rounding the spine may lose a bit of aero but gain nice power and maybe a bit of comfort (less weight out on the elbows). no question really, just stream of consciousness as i get ready to leave work but curious whether this knee/elbow relationship gotten much attention in bike fit circles? i'll put that on the list of things to research on monday when I get back to "work". have a good weekend y'all.
