an interesting thing i've noticed is that while my power balance (as measured by garmin vectors) is pretty much 50/50% on my road bike, on the tri bike its often as much as 45/55%, as well as being a touch lower in total.
i'm not overly bothered whether i'm balanced or not, i just find it interesting that the balance differs between the different positions and would be interested in any theories as to why this might be and anything it might mean physiologically, bike fit or otherwise. i guess the hope being that i might be able to get the left leg power up to match that of the right since it can do it on the roadie.
the other piece of information the vectors give which could be related is that while my right side is pretty centred over the pedal, i typically have a left "platform center offset" of +10 or more (to the outside) on both bikes.
i did note today that my left leg felt like it was going knee out occasionally once i got tired, though i think the balance was pretty consistent even before then
anyone got any thoughts?
