Thing is, the '97 cut off was only ten years old (or perhaps not even that) when this site started so '05 would still be older than the youngest bikes were that got discussed at the start. If it's not current I'd say it's in as a general rule otherwise it just becomes another cliquey, 'your face doesn't fit' site, and in five years everyone will be wondering why the site's dead (and the answer will be because you've chased away all the potential newcomers). Personally I think '95/96 is probably the changeover between old-retro stuff and mid-retro, almost pre and post Shimano M950 as an example. Before that point full suspension was predominantly poor and after that they started to become marginally more reliable and real world useable. You then have another step change around '10 for trail stuff where they really were significantly more reliable. The '97 cut off seems as sensible as any IMO as, like all of these things, it's very subjective based on your own experience and critical time points. In time I guess '98-'08 becomes a segment and then newer stuff it's own category, but at the end of the day a cool bike is a cool bike and if you're after some parts you know what you're after.
