The subject bicycle wears 2nd generation Deore LX which was 1993-1994. 1st generation LX, 1990-1992 used silver crankrams and and silver pivot castings on the rear derailleur, However, since it doesn't have the threadless stem/headset of the 1994 model, it should be a 1993 model. The component date codes should corroborate this. Also, the serial number could be reverse engineered to December 1992, making it a 1993 model.
