It's an rt81 rotor. Used but lots of like left. I've wiped it with a baby wipe but it's not gleaming. Cheers!
Neither ring is narrow wide but would work fine with the right mech. I've got a 38 t hope one on a genesis with a 10 speed rival mech and never dropped the chain. Cheers!

I don't actually think either ring is nw but it's up to you.
