Probably there is almost no difference in stiffness, but the impec looks more sturdy (not sure about this word ok?) I love the new lugs and actually i love the red, yes i like anime The fork looks like the TREK one but better WHat i think is that the frame is a little bit more comfortable, thing i really dont know how u can get it better. Wonder how much is the frame, bmc frames arent that expensive after all compared with other brands.
