I always thought the gusseting depended on the size, the bigger sizes had it under the TT, the smaller under the DT..but thats just what i thought, not any scienctific info.
No, this is a 96 onwards as the gusset is under downtube. The older ones had under toptube.
Defo 96 decals (tho ignore catalogue as it shows older frame style !). It'll have a single bolt mech hanger.
Not sure if they made them in batches and stockpiled them but its seems quite random sometimes what decals
went on. Mine is August 93 with 94 decals on.
