Hey,

First off I have a 2013 Giant Roam 3 Hybrid bike and when I switch to around 6-8th gear my bike starts to make a weird chain scraping noise is that just because I need to get it toned? Because I just bought the bike like a week ago. The sales guy said I would need to take the bike back in a month to get it re-toned is this the cause of why I would need to be doing that? Or is it another underlining problem?

Thanks!
