For the 2 or 3 bolts/parts, the only guaranteed constants between a 2014 bike and a bike which is 15-30 years old are the 100mm OLD front hub, and the rear deraileur bolt size (not the derailleur it's self) spec, everything else could be different (will call the old bike 1990's for now), examples are the headset, 1990's = external cup 1 inch, 2014 = ZS tapered, Front deraileur 3 different sizes & band, handlebar 1990's = 25.4mm or 26mm, 2014 - 31.8mm or 35mm. Could list all the rest of the parts and have multiple specs for current and old bikes.
