good luck with that! i have a 6mm skeletal discrepancy, and it made enough of a difference (shims fixed it). i can't imagine how much cm's difference would jack things up. hope your doc and pt can get you on level footing.
Yeh it's somewhere between 1-2cm
The amount of reach the legs have is not even close to even. My saddle height is 72.3cm for the left leg and to get the right to actually be able to complete the full pedal stroke comfortably and putting power down it should be ~71cm or even less. If I drop the saddle below 72cm my left knee gets really mad really fast so that is a no go, we will see what the doc says I guess.
Have a doctor appointment today to hopefully get some xrays or something to figure out what the heck is going on, needless to say this explains probably all of my bike discomfort...
