Hi,

I'm playing with an old Trek and would like to locate Shimano 600 parts of similar vintage to make it a good riding/shifting winter bike, etc.

The brake levers I have are Shimano 600 etched with "BL-6208"

SO, Do all Shimano parts of that vintage (i.e. same year) have the same code?
Meaning: would a crankset, FD,RD, etc. have the same code even though they were different parts?

Extrapolation of this idea would look something like this I guess:
BL-6208
FD-6208
RD-6208

Thanks,
PJBAZ

Shimano does not have model years. Each part has model numbers with a prefix to indicate what type of part it is if it's not already obvious.

7xxx DuraAce
6xxx Ultegra
5xxx 105, I think

7400 8-spd DA
7700 9-spd DA
7800 10-spd DA

Etc., etc.

An FC-7700 produced in '97 will be the same as an FC-7700 produced in 2003. If there were any changes made, it would be incremented to 7701 or 7710, etc. If it was a whole new redesigned group then it would be 7800, etc.
