Anyone have a good estimate of what percentage of a rider’s weight is on the aerobars and on the seat at two different positions:
-fully aero
-non aero riding.
my guess would be about
-40/60 for fully aero ?
-30/70 non aero ?
( bars/saddle, percentage )
depends on lots, but i’m looking for an average rough estimate…
thoughts?

my guess is 70% back /30 front in roadie…45 back /55 front in aero…sloman puts out some stats in one of his articles on bike geo, i think…the old, sit each wheel on a scale and measure is ‘somewhat’ misleading, i think because you put a lot of weight into your pedals which decreases the weight on either end…or maybe pedal weight/force is more back since they are closer to the back? analcycling probably has it figure it out…maybe pedaling takes up 30% of the weight, skewing it to the back some, then, in aero, 30% on the seat and 40% the arms? so if 2/3 of the pedal weight is back, that would be a 50-50 distribution…???
I think it’ll be more like 55% rear/45% front (measured at the wheels) for EITHER road or tri (at least it should be for balanced handling), or something close to that (53/47, etc). The problem comes in that bike manufacturers are afraid, I think, to make bikes that will give that weight distribution for fear that they’re too different than the roadie market, and so we have bikes with really short front-centers, and thus more weight on the front wheel.
Dan’s Geometry Experiment articles go into this pretty well.
As for what that means with the weight on the butt/hands… Don’t have a good answer.
but but in the winter I have a some what larger gut so the balance of weight isn’t the same.
or is someone is like fat headed it could change .
I will not go talking about the womans side of weight distribution
