"When blind folded, riders have no idea about the length of their cranks" . I experienced the discovery of unusual crank lengths twice, both on used bike purchases. Just jumped on after adjusting and oiling and couldn't tell what felt soooooooo different. It was those 172.5's!!! I'm a 170 (on the road) man. Took about 6 strokes to tell something was up. Another 4 to figure it out.
