While the pure aesthetic beauty of the Orbea Orca is apparent, its beauty from a design and engineering standpoint is also equally noteworthy. The Orca Gold is available in a Di2-ready frameset that cleanly integrates Shimano's award-winning groupset with minimal disturbance to the bike's gorgeous aesthetic. To unobtrusively mount the Di2 battery to your Orca frame, you'll need this Di2 Battery Bracket, which mounts the battery below that left side chainstay, conveniently out of the wind.
