May not apply to anyone else as I am in my 70s but after experimenting with a couple of my bikes the results had me ask my Orthopedist. She believes that at my fit recommended saddle height (set at the bottom of the pedal stroke) the releaf I get is that at the top of the pedal stroke my leg is not as bent so my knees arenot seeing as much compression of the knee cap or the knee moving to the outside with the 7.2mm shorter crankset.
