Good thread, can't believe it's taken this long to appear!
My mystery Bianchi, in it's different guises over the past couple of years:
Summer road bike:
Winter road bike:
Winter SS commuter:
She's currently mostly disassembled, awaiting my fixation with my mountain bike to break so I will build her back up again. I think it'll be "Summer Road Bike" configuration. Maybe with fresh paint.
