doh...i mis-read the initial post...i thought it was an older bike not a 2003. So yes you don't have to worry about rings and chain on it, the ones you have will work just fine just like jekyllrider said.

Also the XT v's work just fine as long as you set them up properly like a2psyklnut said...except I wouldn't go with a credit card thinkness...go with something thinner to set up the toe-in. A credit card may cause to much toe-in and the pads could wear faster and not as evenly. But if it doesn't work..then try something thicker. Later all.
