Hey guys, i know there is another thread going atm about converting to 9 spd, but this one is different, sort of.

Its my birthday soon, which hopefully will mean a cash injection for me, my question is, i understand that 8 spd parts are becoming harder to come by and i've been thinking for a while of switching to 9spd but i dont have the funds to do it, but now, hopefully i can.

In order to upgrade from an 8 Spd set up, to a 9 spd set up, what will i need to change? I bought a set of XT shifters about 3 months ago, and was wandering, would i have to replace both shifters to a 9 speed, or will it still work the same if i just bought a 9 spd shifter, and left my other shifter on? (trying to save abit of money if you havent guessed :D)

Next question, i have a Specialized Hardrock Sport, with a set of Alex Rims, on the rear wheel the hub is Shimano m475 model, will i have to change out my wheelset in order to accomadate the new 9 spd Cassette?

As for the Front and rear deraillers, they can be left as they are if im not correcct? they will still work from an 8 speed goig to a 9 spd, i may upgrade my rear mech if i have the funds, my old one is starting to show its age a little.

Final question, will i need to change my chain? Im not sure whats on it at the moment, i was thinking of getting a Sachs PC69 chain, as it seems cost effective, and will do me for a while, as im not particualry hard on my equipment.

Any help would be greatly appreaciated

You can get away with replacing the right shifter, rear cassette, and chain. You may need new chainrings as well, but you can probably get away without. Since the overall rear casette spacing doesn't change, there's no need to change the rear der. You may need a little tweaking on the front der to get it to work right (narrower chain) but it shouldn't need to be replaced. No reason to go with a PC69 - the 59 will work fine and is less $$.
