I don’t own a modern bike but a couple of weeks ago I rode with a few guys from my neighborhood . They all have modern carbon bikes but my 1975 Colnago got a lot of attention. I dunno , I think it is about the memories of a time gone by. Most times when I’m out and I stop for a refreshment I get someone that had a similar bike when they were young or they always wanted one. Quite often it is a happier more care free time.
