So I discovered a bit of an issue in my form on yesterday's ride, actually it's kinda a big one. I have a pretty regular tendency to cant my left knee in towards the frame when I'm pushing on the left side. Obviously this is a bad thing (I'll give you about 800mg worth of reasons why.) But is there something I can do, other than spend every spinning moment focusing on keeping my knee straight, to fix it? Could there be a reason why I'm doing this? I'm not causing myself crippling pain but whatever that does to my knee can't be good long term.
