Doing this from memory, no sources provided!
The 109 speed RD is notable for its 8 wheel pulley.
Last year Super Record was 1986 (maybe ‘87). The last year SR had the non fluted crank arm. Corsa Record (C-Record) overlapped SR by one year and from that point the hierarchy was C-Record, Victory, Triomphe for a couple years. Super Record came back in 2009 with 11 speed, the first year it had white labels on the RD, crank etc, so that’s the significance whenyou hear “white label Super Record”. The “titanium” designation for the most part
AFAIK really just signified small bits like fixing bolts, etc. The Record Titanium brakes are still mostly aluminum I’m pretty sure.
