Cracks in paint on aluminum frame I noticed some small cracks in the paint on my aluminum frame bike. The cracks are clustered around the rear brake boss, and only on one side (NDS). The bike is from 2011 and has been ridden over 10,000 km. Just wondering if it's just cosmetic or something I should be worried about.
I believe the cracks are just in the paint, not the alloy.

Only the white paint is cracked, not the black, the cracks are evenly spaced and run in all directions rather than the single direction a stress crack would follow.
