Ok. So I finally hooked up my trainer. Boring as hell.

But like swimming where I found that I was weak on one side, I found that when I pedal with one leg at a time,
- I am week from 11 o-clock to 1 o-clock on both legs...
- weaker on the left,
- and jerky on the right.
I am pulling up with each leg on the stroke.
I was fitted to my bike in the aero position a year ago.
But maybe I am just not used to it? Or is this a sign that the crank arms are too long for me ? ??? Anybody messed around with this... is this normal?
When I ride on the road, using both legs, maybe this explains why I feel like I am fighting my pedal stroke and waisting energy there?

Don't know if this adds to the problem, but I am using a road bike with aero clip-ons.

Thanks!
