What's the difference between an aero crown and a unicrown crown? I just found out that the 2008 Globe Sport has been recalled and I'm not sure if mine is 2007 or 2008 and I can't for the life of me, find my receipt! I'm pretty sure, though, that the 2008 model has an aero crown. Pics of the difference would be appreciated, too. If I checked the fork, where would I find the manufacturers mark?

Thank you in advance.

EDIT: Also, if possible, I'd like confirmation that I'm correct about the 2008 model having an aero crown fork and the 2007 model having a unicrown fork.

Praise the Lord! I found my receipts and I bought the bike in May 2007. I kinda knew the difference between aero and uni crowns, but I had to be a million percent sure about not having a bike with a defect, because my bike is black and the 2007's colours are listed as blue or gray only, while the 2008's are listed as bone or black. I'd still like to know where on the fork I could find the manufacturers mark.
