Raising it on the other hand even slightly above a certain point causes problems with saddle comfort and the back of my knees. So I settled on a saddle height a good 5-10 mm below what I could still comfortably pedal. Power was totally unaffected by running that much lower, even on long seated climbs.
Interesting. Assuming saddle height is based on full leg extension, one should adjust this for cranks. Ditto saddle fore/aft, and hence stem length, if you want to keep the same “fit” with shorter cranks.
I realize this is not a rigid geometry issue, but hypothetically if you want same positions you would need to adjust all three of these.
