Sea Otter: Ultralight sub-16lb Cannondale Flash hardtail on display

One of the undisputed showstoppers at this year's Sea Otter Classic was a special Flash carbon hardtail hanging up at the Cannondale booth. Only it wasn't some prototype or stock machine but rather an insanely light Shimano Dura-Ace Di2-equipped rig built for Cannondale by Newbury Park Bicycle Shop in Newbury Park, California.
