I have one that has just a teeny teeny white dot from where my head scraped the pavement when I was going about 20 mph in a paceline. My husband went down in front of me when the guy in front of him slowed unexpectedly. Then I went down.
I will PM you later. Would love some AZ bike shwag. My husband has an ASU jersey, but I guess my alma mater doesn't think they need to make women's cycling jerseys....
