Can you help to identify these frames, bikes or parts?

Hi guys! Could anyone help me identify this frame?

I have some info in case it might help:

• Carbon fork: Trigon
  
• Brakes: Campagnolo Veloce
  
• Wheels: Miche XPress
  
• Crankset: Miche Xpress
  
• Single freewheel: Sturmey Archer
  
• Chainring: Gebhardt GTP
  
• Seat: Bombtrack
  
  

I'm interested in buying this bike but I'm a bit sceptic about the frame.
Thanks a lot, any help appreciated!
