I bought this bike for my son. When riding with him I hear his chain slapping all around. So I'm thinking about switching out his derailleur for something with a clutch. It currently has a micro shift 8 sp. Has anyone put an acolyte derailleur on this bike? The M5185 has a clutch and I think will work with his freewheel cassette.

What do you think?

Title says it all. I see a lot of chatter, but what's going on?
