I'm a little confused by how the pictures of the "racing bike" and "mountain bike" depict bicycles that are more modern than the year listed. The "racing bicycle" has even been modified to have radial spokes, a very resent development (and seldom if ever used on the rear wheel). Is this because they are meant to represent a style of bike that's existed since the year noted not how the style looked at the time? If so could we make this more clear? I'd also like to edit the "racing bicycle" to have a derailleur as by far most road racing bicycles have one; unless anyone objects of course.---Keithonearth (talk) 06:27, 22 November 2008 (UTC)
