Are you pushing too high a gear? Is the crank a different length than the other bike? If you set saddle height based on the other bike, then did you more correctly measure to the pedal at the bottom of it's stroke or wrongly from the BB?
All good questions and I can only answer that I tried to measure consistently between the two bikes. The seats are different and I am trying to use the BB center as my point zero then run the ruler to match the angle of the seat post to set seat height. My crank arms are the same length so that is a constant. As far as pushing too high a gear I make my selection as to the load I feel in my bad knee without spinning out. I have been making a concerted effort be conscious of my rpm and knee/leg over the pedal and not splayed out. I also have to take into account the 47 years of wear and tear on my legs as a plumber so there is a definite base line I need to recognize.
Thanks again all for your input.
Be safe, Frank.
