Upgraded Argon 18 Gallium

My customer's upgraded Argon 18 Gallium. Before it has got Shimano 105 R7000 grupset and DT Swiss PR 1600 wheels. Remove all parts, grouppo, wheels, contact zone eq's and assembled new one:
– Shimano Ultegra R8150 Di2 12 speed groupset with RİM BRAKE. Yes! Really rim brake!
– Mavic Cosmic SLR 40 wheelset with Vittoria Corsa
