Yeah, I calculated the worst possible case. You would think the manufacturers would have recognized the existance of compact cranks several years ago and constructed their braze-on tabs accordingly. Maybe compacts weren't a consideration in '04 when the OP's bike was manufactured.

As to a clamp-on adapter, I expect this frame doesn't have a round enough seat tube to use one or Trek wouldn't have bothered with the tab.
