I’ve owned a fair few bikes before and not experienced this issue before.Both if the Giant bikes which proceeded this one week well finished so wouldn’t relate the issue to cost…….I have a photo which I will try to share later, but the seatpost is heavily scored rather than scratched, and there’s traces of metal filings on the seatpost and within the seat tube, which would seem to indicate it’s more than a slight cosmetic issue.
To me it seems as though the inside of the tube wasn’t finished. Thinking back the demo bike also had similar scoring. I wonder if it’s a general problem during manufacture or it’s not being picked up when the bikes are be built in store.
I’ve fired off an email to Boardman customer services just now to explain the issue as I’m not wholly confident that the local Halfords won’t just try to palm me off with another seat post.
