Here's a Spesh diverge Geo chart.. how many BB drop variations are there (Jamis has 5 different drops depending on frame size). Spesh also with only 2 different chainstay lengths, Jamis has 4. Also notice how the Diverge Trail just keeps dropping as you go up in frame size, vs making an attempt to keep the trail (bike handling/feel) in the same ballpark through the sizes.
Sorry if I wasn't clear enough. What I mean is that Jamis is boasting about size-specific geometry details the same way Specialized is boasting about the carbon layups - like it's something new and special. It's not, having proper geometry for every bike size (including chainstay lenght, BB drop and fork rake) is something that manufacturers have done for decades. Effectively, Jamis is just boasting that they are not cutting costs in this area like many other current manufacturers do, while conveniently ignoring the fact that numerous other manufacturers have quietly been doing this for longer than the Jamis has been in existence.
