The most overated bike I ever owned was a 1972 PX10, purchased new at Mulrooney's for $249. I couldn't trim the front derailleur so it wouldn't rub the chain on hard climbs or sprints; thinking the crappy Simplex derailleur and Stronglight cranks were to blame, I switched them out for Campy NR. That didn't fix the problem either; the whole frame was to blame. I sold that bike in 1975 and never regretted it.
In 1973 I bought my first Paramount, a P14 track bike. I still have it and ride it at least once a week, and it is still a joy to look at, with it's nicely shaped and filed lugs. The original Campy bottom bracket and hub bearings are still going strong, with many tens of thousands of miles on them, and the 531 frame hasn't "softened up" a bit in 33 years. The steel track bars and stem were replaced with aluminum Cinelli many years ago, and the bike is now equipped with Profit clipless pedals for the sake of comfort.
My 1974 P13 is now living a life of genteel retirement. I upgraded the components on that bike during the 80's and continued riding it almost daily. Several years ago, I decided to return it to all of it's original Nuovo Record splendor. I'd ride it more now, but the toe straps make my big feet hurt, and I don't want to wear out the Detto Pietro shoes that go with the bike so nicely (and are hard to replace).
For the sake of this thread, I just weighed both bikes. The all original ten speed is just a shade over 22 pounds, and the fixie is right at 19 pounds. Both frames are 24" (Schwinn didn't mess around with fancy-shmancy "centimeters" back in the 70's).
