Hoi. My mate finally got his Orbea all these months after we ordered our bikes at the same time. Nice looing thing for a cheapie. It's got a problem though. Everytime he shifts onto the big ring on the back the spokes make a dinging noise. Turns out it happens whether he's pedalling or not, so I'm pretty sure it's the rear deraileur touching the spokes. The thing has Shimano R500 wheels and Tiagra rear deraleur. The rear deraileur is shifting properly, so I'm not sure what kind of adjustment we can do to it. Fool wouldn;t listen to me and bought it from the next town over, so it's a bit of a pain to get it back to the shop to get them to look at it. So any ideas?
