Here is the Di2 battery mount and cable port on the left chainstay. The port is barely large enough to get the zip ties through.  It is 7mm x 8mm, the Shimano requirement, but I might have to go to 7mm x 9mm to accommodate for paint millage.  Don't want to chip it.

An old Cinelli brake bridge and a new Paragon that we will use on Dans frame.  Uncut and undrilled, the Paragon is 10 gms. lighter while retaining the traditional look of the Cinelli.  Chasing those grams!
