I don't think Moderncyclista should try to sell something she believes to be defective. Bad karma.

What are the chances, Modern, that some cyclist-hater type saw your bike parked in the sun and pulled a prank by putting some kind of black dye all over your saddle? Like the shoe polish-on-the-binoculars-eyepiece prank.

If not, I'd certainly write to Brooks and let them know about the problem. You might get reimbursed for the shorts and a new saddle with better dye.
