I'm not sure if this is the proper section so forgive me if it's not. I'm just getting ready to buy a bike and I'm wondering what kind. I can't run any more so I'm going to ride for exercise and recreation. I don't plan to do any hard trails like I used to. I used to have a road bike (80's Bridgestone) and a mtn bike (91 Giant ATX). Now I plan to mainly ride the street but I still want to be able to ride dirt paths and simple trails. So I was thinking cyclocross. I want to be able to get some long rides in eventually (50+ miles). What do you guys think?
