I recently purchased a new Giant Defy Advanced Pro 1 (2017). Its Shimano Ultegra with hydraulic discs. The front shifter is a 'triple', the front chainrings being a compact double. When changing down two clicks the front derailleur shifts to a position where a small third chainring would be positioned. Can anyone tell me if it's normal to supply a compact setup with a triple shifter. Is this a standard Shimano Ultegra setup.
