I only really know about the early stuff as that's when I bought it - the new fangled titanium hubs came later
First discs became commercially available and didn't use spiders in 91 but some prototypes were released earlier (I think for tandems).
Spiders came out very early in 92 still along side the solid discs, I think what you got depended on whether you ordered anodised or plain hubs, the plain ones being the newer type.
The calipers initially were cast and hand finished - cnc calipers came in in 93 I think.
