Looking to upgrade my drivetrain, was looking to get a Sunrace csmz903 cassette (basically shimano) and xt derailleur but unsure if I will also need to upgrade chainring and chain to Shimano. I have a Raceface chainring and SRAM sx drivetrain currently but just was wondering if I needed to shell out extra money for the all round Shimano get it to work or if it would work fine with the Raceface chainring. Thanks to anyone that could help!
