I ride vintage racing bikes because of the way they fit. I am 6’ and have a 35” inseam so very short trunked. The tighter cockpit with longer seat tube is very comfortable. I had a friend who built his own frames back in the seventies and he did centuries a lot . He fitted me to my first racer and I would street race anyone who was on the road. Sometime in my fifties I decided to let that go and enjoy the ride. I am 65 now and still push myself but I don’t worry if someone passes me. I also started a vintage racing bike collection and spend some time wrenching on them. I still ride quite a bit and occasionally I will find myself pacing another rider and even passing them just to prove to myself I can. It’s an ego thing , but most of the time it’s about the ride and scenery . Joe. joesvintageroadbikes.wordpress
