I have two bikes that are very similar in weight, handling etc. The only reason I have them both is that I bought one while the other was being repaired. In order to distinguish them a little bit, I set one up for climbing (compact 11/28) and the other for local short or flat rides (standard 12/27). In the winter I also leave the "flat land" bike set up with lights and so forth so it's not a big production to get out on it for night rides.
