Shimano LX rear derailler RD-M580

im looking at this derailleur and it says its "rapid rise" and "mega 9 speed"

do I need special shifters for rapid rise?
Can I use this with my 8 speed set up?

Normal shifters will operate the "rapid rise" derailleur just fine. The only issue is that the gear indicator numbers will be backward. It'll say "1" when you're in the smallest rear cog. To me that's not much of a problem.

Since the rear derailleur guides the chain from the center it doesn't care how wide the chain is or how many cogs the cassette has. It'll work with an 8-speed shifter and cassette just fine.

ok...thanks for the reply...

so what im gonna do is get a long cage Shimano LX rear derailleur

what I have gathered is that even though it says 9 speed, it will work with my 8 with no problems.


MY ONLY CONCERN at this point is that its "rapid rise" and as a poster stated earlier, it may reverse my shifting on my current shifters...I.E. if i shift down with my trigger now...it will reverse with a rapid rise derailleur and shift up with my trigger...is this true??? (by the way Im using ST-EF29 ez fire shifters)
