What does "thrust" or pick up in a bike depend on?I recently purchased a 1993 Speciallized Allez Comp and its noticeably faster or has more thrust when I want to take off than otherbikes I've owned including my 1987 Pinarello Montello a true racing bike.I think this phenomenon of power response is called energy transfer to the wheels or something like that.I also had a real noticeable power response with my 2000 Litespeed Classic which I have since sold. Is it dependent on the wheels?The specialized has Mavic Open Pros,and the Litespeed had Mavic Heliums while My Pinarello has Open Sports a cheaper wheel.Surely its not just one thing but perhaps people could enlighten me on the subject a little.Thanks!
