The imbalance was found when i tested Look Keo power pedals. I did not believe it but Wattbike showed the same imbalance and subsequently Vector showed the same.CoachFergie said:The Garmin head unit does not measure force vectors (yes how ironic) from the pedals yet. The only meters that do are the Pioneer and the Rotor models. One would expect they would measure the force on the upstroke.
Why do you think there is an imbalance and under what conditions does it approach 60 / 40?
And going off topic why do you think measuring force vectors around the pedal revolution will offer a solution other than spending time trying to achieve 50 / 50?
The imbalance is less at higher powers and higher cadences but always there even when i consciously try to put more effort into the weaker leg. The weaker leg also seems to show more of the imbalance as fatigue sets in.
I don't worry about it as I find my limit to performance is my breathing rather than my legs and at or around FTP provided the cadence is higher the imbalance is only a few percent.
I'm interested because the weak leg is in fact the leg i would say is stronger as it is the leg i would kick a ball with but I have had serious injuries to the knee and hip - I think perhaps i subconsciously hold back with the leg as some sort of protective measure.
I'm just interested in finding out why my injured leg has less power particularly at higher forces lower cadence. Is it just pushing less hard or is it slow or late and pushing for less time each stroke - no idea?
