A moment of distraction, a slight drift, a parked vehicle. Boom goes the bicycle.
Total damage: destroyed right Campagnolo Veloce shifter body, cracked and bent right fork leg, smashed helmet, torn jacket, scuffed saddle.
Oh, and a short trip to the hospital for some x-rays, confirming no broken bones but nasty deep bruising and a shoulder that is immobile for the time being.
I'm just glad this was the winter bike, and it's January, so there's lots of time to fix it.
