Not quite old enough for this thread (I'll turn 64 in September), but I've probably been riding track bikes longer than most, starting with a Helyett Speciale Tour de France (!) track bike in 1964. Reynolds 531 throughout, all French components. Rode it unsuccessfully in the U.S. Track Nationals at Kissena Park in Queens, New York, that same year. All the kids from Chicago made fun of my 10-ounce Dunlop tubulars. They all had orange Clement Seta tires. Fair enough; I was there only because I was the only Intermediate-age kid in Connecticut with a track bike, probably.

The best-riding track bike I've owned was my 1982 Bianchi Eco Pista. Still own three, an all-531 1968-ish Peugeot with a French Campy Record group, a Specialized Langster from the first year of production, and a Felt TK2.
