That crank length thread is a bit heated over at i-bob. I've also been wondering if I should get a shorter crank because of left knee pain, which tends to start and gets progressively worse at the 20th mile mark. There are quite a few crank length calculators out there, all giving me results ranging from 165mm to 177.5mm.
I currently ride a Sam with 175mm Sugino triple crank (82.5 PBH).
