I'd like to know more about how much actually changes on a typical bike from year to year. I notice that color is frequently different, but aside from that, do models really vary much from one model year to the next, and if so, how so? Perhaps it's my inexperience speaking, but I don't see much difference between 2005 and 2006 models, for instance, although the price does seem to go up.
How do bike model years compare to car model years? What I mean is, with cars there's usually a bunch of supposed improvements throughout the car every year even if for the most part they look pretty similar. But is that true on bikes as well, or is 'model year' pretty meaningless, except as a way of knowing when the bike was manufactured?
