I am very new to this thread and seeking help from an experienced bike enthusiast. I just purchased the aforementioned bike in the title and after bringing it home for inspection(bought brand new from a shop mid NYC which doesn’t allow entry)I noticed a scratch/marking behind the seat post. I was advised to take the seat post out to inspect the inner area to see if it’s structural damage. I will post pics below. My question is this going to bite me in the behind later down the road or should I take it back. No bike shops had this anywhere so I had to drive an hour plus each way to find it. Thanks in advance , I may have botched the format.
