You have to forgive the mechanic for any errors - he is actually a carpenter if his workshop is anything to go by.
My god, the more I look, the more I pick up on dumb errors. Is this one of those "Our illustrator has made 100 deliberate errors. How many can you pick?" type of games?
One brake lever, and a modern one at that given the shape, feeding two brakes via 3 cables, one of which isn't wrapped under the bar tape and looks to be on the outside of the drop. Or is that how the new SRAM does it? The cable wrapping integrating with the lever is damn neat, that's the sort of style we expect from Campagnolo.
About the only thing AI got right (assuming it wasn't asked to "draw me an artisan in a workshop working on an impossible bike") was the dude doesn't have 6 fingers.
Though I must say, I often remove the rear wheel and install a dummy hub when I install a bottle cage with an awl - so that bit is correct.
