Shimano Alivio M430 9-Speed Rear Derailleur: Shimano Alivio Rear Derailleurs are direct-attach and have an advanced light-action design. Advanced light-action design. Teflon-coated bushings. All are direct-attach rear derailleurs.
Strengths: long cage.properly cleaned and lubed it shifts nicely. pair it with m430 alivio dérailleur and teflon cables and it is better. good-looking.
Weaknesses: off-road chains slap. late shifting when in load. good enough for its price i think.
