Is it the front derailleur that rubs the chain ? That happens to some degree on all bikes, so you need to make small adjustments ("trim") as you shift the rear up & down the cassette. You may have a "friction" shifter for the front, and indexed or friction for the rear.

Well, you first have to answer the question about indexing. Does the right/rear shifter "click" with each gear shift (indexed), or not (friction) ?
If it's indexed, then you need an authoritative answer to the question: "Is my Microshift 8 speed drivetrain compatible with Shimano 8 speed shifters" The "Mechanics" forum has the best percentage of correct answers.
