shimano cog compatibility

Does someone have the complete details on building Shimano cassettes
from individual cogs? I know of Sheldon's page, but I don't quite
understand the color coding. Aren't you restricted by the previous
cog as to which you can use?

Jon.

You should try to get the shift ramps lined up. Mismatches are not as
bad on larger cogs, 25-30 as on smaller ones. I've filled down the
wider tab on the cog and rotated it until it lined up or was very
close.

is there an easy way to determine which cogs are worn without trying
out each one ?

the cogs can go on [censored] nilly. I read that. you can for example place
your two favorite cogs smack in the middle lining up with the CR's for
greater longevity.

Sure. compare the old cogs to new cogs. the shapes are different.

Rohloff makes a tool so that you can assess each sprocket
without a road test:
