[KnottedYet]

depends on your femur to tibia ratio.

the biggie for this one is when your pedal is at it's most forward position (3:00 and 9:00). A string with a weight on it dangled from your kneecap should intersect the crank either at or a cm or 2 behind the pedal spindle. (or your metatarsal heads/ball of the foot)

This prevents you from damaging the knee joint by putting pressure through the leg when the knee is out beyond the met heads. (just like you shouldn't squat by pushing your knees out beyond your feet and lifting your heels off the ground)

Most bikes start off their lives set up for the shorter femur to tibia of the standard male leg. So if your fitter put your saddle down and back to be more appropriate for a woman's longer femur to tibia, it might feel different.

If you are concerned about it, ask someone to dangle a string off your kneecap while you have your pedal in the 3:00 position, and check where the string crosses the crank arm or your foot.
