Hmmm, I have read most if not all GP wrote, and while message is received, numbers rarely stick. So, I got out my tape measure: with a PBH of 91, and Keen bike sandals with a sole of 1.9, my saddle height is 67 cm to center of crank. I don't think it is the numbers (36", .75", 26.5"), so, I am not sure why my numbers seem out of whack. My bike is 60cm Cheviot, saddle is a Rivet Loveland, and pedals are Grand Cru Sabots. Perhaps it is because I have a 175cm crank instead of the usual 172 (an idea I got from GP for a leg length/arm length ratio issue).
