I was ogling another bike on ebay, a pretty 1970s era Bianchi road bike, and got to wondering about why I would be thinking about another one, especially since I hadn't put that many miles in this year anyway. Just looking for that "perfect" bike (as opposed to the pretty darn good ones I've got?) Or just the desire to see what it would be like? Is this the root of N+1? (the Bianchi has been bid up past the price I'm willing to pay---so I'm safe this time!)
Anyway, instead of choosing which bikes you would give up, how about if you were starting over--what kinds of bike would you choose now (vintage, steel, road, commuter) for your first bike, then how many different ones; not necessarily particular brands and models but if you have a strong preference go ahead & say so!
