I'm on the 1 year plan, right now! First road bike bought in Nov. of '09. "Outgrew" that starter bike pretty fast and got my new/current ride in early Dec. of last year. Now I am eyeballing a cyclocross bike before Fall so that I might get in on some races and have a bike more suitable to riding when roads are snowy/slushy and on our unpaved roads (they can take studded tires for snow and ice). I hate not being able to ride outdoors some year-round, so having 2 different bikes will allow me to not be stuck on the trainer so much all Winter.
