Here's a question, in short, about if my zero offset seatpost & very little setback moves my weight distribution too far forward on a road bike, and if so, is a better solution to go with a steeper seat tube angle and a normal amount of offset, effectively giving me the same contact points but bringing the rear wheel closer to where it should be for weight bearing purposes.
I've read many articles & comments that correct weight distribution (55% rear/45% front) is as important as a good fit, at least for optimal performance. (Keith Bontrager argued in the past that 55/45 was actually more important than KOPS.)
I'm in the long legs/short torso club. I've been fit, using both a pro BG fit and KOPS, with a very forward saddle position & very little setback, requiring a zero offset seatpost. (I guess Lemond got the long femurs and I got the short ones.) I'm pretty flexible and have high saddle to bar drop, although I usually need a short top tube (or short stem) and short reach bars- currently liking my Dedas- so that I'm not too stretched out.
I recently rode an older TT bike with a 77 degree STA but converted to road bars and zero offset seatpost. A little weird of a setup, but, it felt good and got my 3 points of contact right where they needed to be. It made me wonder about the more relaxed geometry of my racing frames- with their slack seat tube angles and longer top tubes- and if my push forward to get the same fit is taking too much weight off my back wheel.
Any thoughts? Other than yes, I would benefit from a custom frame, and I wish I had taken physics in high school?
Thanks!
