Rubbing noise while coasting but!....


Hello Everyone, looking for some advice. I have giant explore e+ Recently it started making a rubbing noise but only when coasting and only when my right pedal is in the down position. If I switch and coast with left pedal down but the right pedal up noise is gone. I recently had the brakes, gears adjusted and Im fairly sure its not the brakes rubbing (they were when I first got the bike. LBS did a terrible job setting it up from the factory). Any idea what this might be? The noise is present in any gear but again, only when right pedal is down and Im coasting. Cant here any rubbing when pedaling.
