I ride a Lemond which was made by Trek, vey similar wishbone in the back. The "25" Armadillos rubbed off some of the paint inside the triangle, pretty tight fit. But the Dillos do run wide with the ridge type sidewalls which is why I would think the 28's in a Serfas would be too wide on his Trek.
I run 28's on our tandem but there is much more clearance.
