Well doesn't everyone need another tandem project?
Anyone have old catalogs? I'm thinking 1991....
There are no tandems in the 1990 catalogue. The 1991 shows a Quatrefoil (Deore DX) and Quatrefoil LE (Deore XT). I have nothing for 1992. An online 1993 catalogue lists a Quatrefoil (Altus) and Quatrefoil LX (Deore LX). Unfortunately, there are no pictures but the specs for the Quatrefoil LX list rear cantilevers, as opposed ot the U-brake. So, maybe it's a 1992 or maybe GT had 2nd thoughts about cantilevers for 1993? The serial number and component date codes may provide some clues.
