I recently bought an early 80s Motobecane Mirage. After taking it for a 10 mile ride tonight, I was very impressed with the ride and handling. I've never ridden a bike that handles like the Moto- it is so willing to change direction yet extremely stable. It is the complete opposite of the Giant OCR3 i just sold. Looking at the bike i notice that it has a much longer wheelbase than my Peugeot PKN10 or my LeMond by a bit more than 3 inches. The chainstays are noticeably longer on the Moto. How and why is it that longer wheelbase improves handlling?
