Cassette size for sram red?

p807com

Will I be able to run an 11-28 cassette with a Sram red rear mech? Also, do I have the option of shimano cassettes with a sram chain, i've heard the sram chains are too abrasive for shimano cassettes? cheers, Rich.

never had a problem running sram chain on shimano cassette
