Bicycle detail

I left my bicycle chained to a rack on the sidewalk of Cough street right in front of my gym at 10am on Sunday morning, September 3. I spent 1 hour at the gym and returned to my bicycle lock cut (it was made with 8mm square, hardened-steel chain links) and bicycle gone. There are a few identifiers unique to my bicycle: phone mount says “tackform”, saddle says “gel” (not original to Kona bicycles), chain is rusty.
