billydonn, when i "mirrored" the two bikes i measured the length from the bars to the seats, etc.so i don't think this is the problem. that's why i was mystified as to what it could be. i'm surprised the lbs guys never mentioned the cranks when they worked on the bike. i'm guessing since i never mentioned it they didn't consider it either. in their defense i was more concentrated on getting the cockpits to match. i'm bringing her in to the shop today & will know more. i wonder if i need expensive cranks or r they all about the same??
