If you look at previous few photos you can also see considerable evidence of some kind of spillage down the side. Could have been some kind of training mishap, though, and not a defect

But it does raise a question I had that may have already been answered about this thing. If you lay the bike down with a full load, does it spill? E.g. sometimes you can flat in the middle of the desert (or Queen K) with nothing to prop the bike against. So you have to lay it down.

Edit: OK, Tim Don and Lucy Charles also have evidence of spillage. And Tim Don looks like he has a bottle wedged between his saddle and the lid. And it doesn't really look like that was an *intentional* placement. It looks like it was wedged there. Am I wrong?

At first I thought the OP was just hate-mongering. But now I'm starting to agree. It looks like there might be a spillage issue. Maybe hitting bumps, etc. And it's not great that the spillage can go right onto the drivetrain. A sugary RD isn't going to be ideal.
