I know you've posted many, many times the information on how leg pain symptoms can be an indicator of how your bike is fit and how to make the adjustments. I couldn't find how to get back to one of those posts. Could you send me a link?
Thanks!

Melanie:

That post was on the older version of the forum. With the update we had this past May, all those posts were lost. So here it is again:

Knee Pain Location as Indication of Fit Problems:

Location- Front of Knee
Causes: Correction
Seat too low: Raise Seat
Seat too Forward: Move Seat Back
Excess climbing: Reduce climbing
Big gear mashing: Spin at higher RPM in lower gear
Cranks too long: Shorter cranks

Location- Inside of Knee
Cause: Correction
Cleat malposition toes point out: Adjust cleats to bring toes in, use floating pedals/cleats
Excess pedal float: Limit float to 5 degrees
Excess exit tension: Lower tension
Feet too far apart: Move cleats out (moves shoes out on pedals), Narrower bottom bracket or Cranks with narrower Q factor

Location- Outside of Knee
Cause: Correction
Cleat malposition, toes point in: Adjust cleats to bring toes out, use floating pedals/cleats
Excess pedal float: Limit float to 5 degrees
Feet too close: Move cleats in (moves shoes out on pedals), Wider bottom bracket or Cranks with wider Q factor

Location- Back of Knee
Cause: Correction
Saddle too high: Lower saddle
Saddle too rearward: Move saddle forward
Floating pedals: Limit float to 5 degrees
