Didn't RockShox revise their Debonair since there were complaints from customers that their fork was sitting deeper in travel, without any rider on the bike? Doesn't Vorsprung state that their air spring mods cause the fork to sit deeper in travel at rest, but that this is a small price to pay for the extra performance? Weren't there some frames that offered more negative travel, that looked unfamiliar due to having two dampers? I believe there was some remark that sand dune buggies use a similar setup. e.g. Foes FFR I guess seeing this kind of stuff before has desensitized...
