My one and only velo is a classic vintage '84 Peugeot PH10LE that I bought new. I'm the only classic steel rider in my group.
There's a group that rides from the Rose Bowl in Pasadena the 1st Sunday of every month. They encourage riding nothing newer than 1985, but say to ride what ever you have. I think it's called Retro Velo. I need to check them out one of these days.
