Here are my questions:
1) do I need to change anything else beside the rear derailleur, freewheel, and chain?
2) how do I determine the proper length of the new chain?
Thanks for any advice and observations
1: No.
2: Same method as installing a new chain. The chain should be long enough to wrap around the big chainring and big cog, plus ~1 link.
