Quick question: Does anyone know how does the old Shimano STX component group rate against their new standards (XTR, XT, Deore .....). Specifically the transmission.
No idea really (having not used much of the new stuff) but I have STX 7 speed shifters and they do the job for me.
They sat where Deore sits now but are actually considered a slightly lower notch. If you were to truly rank STX, it would sit somewhere between Acera and Deore.
Okay... so the best breakdown from the 1990s I can come up with is something like this:
Note - I'm only listing M-series groups but this includes the "mountain-comfort" groups designated MC which were later phased in as a new designation at the 400-level and below. Not all these groups coexisted with one another at all times. Also note that in the lower to mid entry groups, the ordering shifts about a little over time with some groups flip-flopping in precedence (STX-SE and STX for instance). You can sort of make out where they fall based on their numbering. I have ranked them by the highest level they've achieved.
XTR - M900, M910, M950
Deore XT - M735, M737, M738, M739, M750
Deore DX - M650
Deore LX - M550, M560, M567, M570
Deore - M540
Exage 500LX - M500
Exage ES - M520
STX-RC - MC33, MC36, MC40, MC41
Exage 400LX - M400
STX - MC30, MC32, MC34
Acera - M330
Exage LT -> STX-SE - MC31
Exage 300LX - M300
Acera-X - M290
200GS - M200
Alivio - MC10, MC11, MC12, MC14, MC16, MC18
100GS - M100
