There's a couple ways to go about it, one you can look up your specific models tech specs I think I recall that one maxing out at 28 teeth or so.. I could definitely be wrong as I don't run Altus. But the simpler method is to see if your RD is short, medium, or long cage. A long cage RD can handle just about any tooth count you can throw at it.
