It is generally good practice to replace the chain when you replace the freewheel.
We recommend the SRAM PC-870 chain for use with this freewheel.
This freewheel will index with any Shimano-type 7-speed shifter.
This freewheel uses the Park FR-1 extractor.
Are you sure you need a thread-on freewheel, not a cassette?
