stolen 2025 Cannondale Synapse

The bike was inside my apartment building’s southeast bike room, chained to another bike. The bike room is immediately next to a door out of the building. Someone was let into the building, broke the chain, and took only this bike. It happened within the last 12 hours. I bought the bike last week and only have the Facebook listing photo. It is a 51 cm road-bike frame with 700cc wheels with black handles. I sawed off some of the bottom of the seat post to make the seat shorter.
