I had my 2008 Fuji Track (58cm, serial number ICF7LO1598) stolen yesterday from a bike rack at the north end of the Michigan Ave bridge over the Chicago River. I saw the guy getting away with it and chased him down Fairbanks/Columbus but he got away. He was a black guy with a silver helmet. Please don't buy this bike from him if you see it for sale.
Also, the guy had my Masterlock u-lock with him and it looked intact, so he must have been able to pick it open somehow. By the way, it was broad daylight and there were literally hundreds of people around.
On the off chance that you are the guy who stole my bike, I will buy it back from you. If you find this bike, please email me at firstname.lastname@example.org.
