Re: 1992 Klein Adroit Sunburst XTR Strata 20/M
I think it's just the photo. I believe the paint color from the opposite side is showing through the holes in the cassette resulting in the dropout in the foreground to appear misshapen.
EDIT:
Turns out the hole appears misshapen due to mildly over exuberant paint application. The paint dripped ever so slightly and cured in that position.
