These are the two road bicycles sitting next to me right now... Both are equipped with mid-range componentry and considered quality frames from their respective eras. Outright performance brought about in terms of frame, wheel, crankset and cockpit stiffness, as well as braking power and shifting capacity, highly favors the 2013 Look 675. I can fly on that bicycle compared to the 1979 Mercian Campionissimo, which is more comfortable for long-distance riding and has that sprightly steel ride quality that no carbon frame I've been on has ever come close to mimicking well.
I have different reasons for loving to ride both bicycles, and personally feel sorry for people who chose to be "haters" of anything having to do with this great hobby. Thankfully in this thread so far I've seen more appreciation for both sides of the story than I recall in previous discussions of this nature around here. Cheers!
