Bikes: 1982 Trek 930R Custom, '91 Diamondback Ascent w/ XT, XTR updates, Fuji Team Pro CF road flyer, Specialized Sirrus Gravel Convert, '09 Comencal Meta 5.5 XC, '02 Marin MBX500, '84 Gitane Criterium bike
my '82 930 uses guides on top of the BB, not the under-channels...
as to colors, in the early days, trek offered pre-painted frames/bikes, or you could order any color /combo you wanted, if it was on the palette of Dupont Imrons they stocked...mine was ordered in dark gray metallic, with dropouts featuring eyelets, even though it has the "race" dimensions/geometry
is the headbadge riveted or glued on? '82 was glued on, 1980 and many '81s were riveted, IIRC.
decal style changed during 82, so they can be kind of misleading.
my frame was completed/shipped during the interim period, and has no decals.
the folks on "Vintage Trek Bicycles" on FB can provide loads of info... they love old Treks, and some have downloaded endless info resources too.
