For short person like me, I get less than minimum 165 (Shimano crankset).
Does keeping as close as to this formula help to make biking more comfortable?
(= no knee, back, hip pain after long rides)
Anyone has experience getting improvement of riding experience when changing the crank length?
Thank you,

Sugino makes a lot of their models (even the "modern" cranks) in shorter lengths like 160mm and the "Mighty Mignon" in lengths from 140-155mm.
If you go too short, you can get that "shoes tied together" feeling, but I think my knees do like 165mm more than 170mm. I'm 5'7"ish.
Whatever crank length you use, it's important to set the saddle height carefully. Going from a long crank to a shorter crank, you'll need to raise the saddle a little. And vice versa.
