BITD = Back in the day.

As in a long long time ago when I was very young. 1960 - 1979 is the usual date range I'm thinking of when I reference things by BITD.

GS when talking about Shimano Derailleur's is a mid cage length rear DR. GS is actally part of the part number of the DR. SS is in the PN's of the DR's that have what's considered a short cage.

Regardless of SS or GS, you really need to know the exact part number of your DR. While many have the same specs, there are some that are notably different in their specs even when they are SS or GS.

One of the places you can find the specs of Shimano DR's is here.... https://si.shimano.com

Might take a while to learn were to look. I also don't like their new format. Takes me longer to find what I'm looking for.
