Just got a pair Shimano LX m580 rapidfire shifters to go with avid levers...but my drivetrain is 8 speed
got to the site that sold me the casette and they said that the SRAM 8 speed cassette is compatible with <paste>(You can use any 9 speed compatible derailleur and shifters for the Sram PG-850 8 Speed Cassette. That includes LX, XT, XTR, & Sram ) ---END

I know the Front shifter is fine with my front derlr...but will the 9 speed shifter work with a 8speed drivetrain**********(cassette and derailleur)

if not Ill just store the shifters till I convert to 9 speed...(a yr from now...)

No go, sorry. The spacing of the cogs is not the same.

thats what I thought so...so the chain and the cassette needs to be converted to 9sp then...
cheers

DONE...answered

oops...forgot to mention derailleur upgrade too...blah

The 9-speed Shimano rear derailleur would work with 8-speed shifters, cassette, and chain (other than 8-speed Dura-Ace). The cassette and chain both need to be Shimano 9-speed to work with your Shimano 9-speed shifters.
