I did a search to try and find out what I need, but the discussion on derailleurs was way over my head. Can anyone tell me which kind I need for a Surly Cross Check with 52-42-30 ring and 12-27 cog? The previous derailleur was a Deore LX. Thanks in advance.
Edit--previous was long cage Deore LX.

In general long cage rear derailleurs are used with triple cranks, and short cages are used for double cranks. You should therefore probably use a long cage rd.
