>>32125 #1 - inside your knee. basically, this has to do with both injury and power. if your leg has an internal angle of, say, 160 degrees instead of 150, you'll probably start losing some power in your pedal stroke. if your leg has an internal angle of say 170-180 degrees, not only will you lose substantial power, but you also risk harming the joints in your knees. because your ankle is basically a hinge, it's possible you could hyper extend your knee(s). if you're doing 90-95 rpm/minute (<--that is pretty close to an optimal number of pedal strokes/minute, though it could vary within a range of 85-100; i ride at 100 rpm, for example), that can be A LOT of potential stress on your knees on a long ride.
on the flip side, if you make this angle too small (like anything below 145... 150 is almost a bare minimum of an angle here), you're going to start getting a lot of pressure on your knees, once again. so basically, 150-155 degrees is where you want to be. 160, tops, if you have really flexible hamstring muscles that can still engage efficiently when your leg is that extra 5-10 degrees straighter.
