They're definitely not just re-badged frames, I was looking at those bikes last night, it's a BMC definitely, it has their trademark tubing. It's aluminium but has very nice, smooth welds. I wouldn't be surprised if they were just team frames, BMC have done that before, just making a few frames for their pros. I should have asked Adam Blythe about them but I didn't get time to. They're quite boring frames compared to BMC's usual frame designs.
