Usually, replica frames are not made in the same mould and have some details that differ to the real deal. For instance SL7 has a different design where chainstay and seatstay meet, front derailleur mount is different and of course, the paintjobs are not 1:1 the same. The difference under the paintjob, we don't even have to start...
In general, they look very similar and most will not recognize it but experts can identify immediately.
This beast here looks absolutely identical to the OEM Foil. And I mean every single detail including the paintjob. I have a hard time believing that they show the fake one here. I suspect they made some pictures when they had the original Foil frame to reverse engineer it for the replica moulds.
