The problem is that you are going from those motobecane that are not even similar to the real motobecane, to a ridley, Basically u went from a 80's minivan to a 2010 BMW sport. U can't even compare them. HAve u ever wonder why some old steel frames are so expensive?... Just sell the old motobecane and get yourself a super nice helmet and a super duper pair of shoes...

enjoy
Hmm did you notice the difference at the 1st pedaling as i told you or not?
