Basic search on Ebay or the web: "42T 120 BCD outer chain ring"
here's the exact replacement ring... Ebay Search: SRAM/Truvativ X0 X9 GXP Chainring 42T 120 BCD Aluminum Black Use with 28T
remember that ANY outer ring you order for your bike, as it is now set up, Must have Shift Pins and Ramps, or you won't enjoy it one bit, ok?
