I think it got an eccentric BB which may explain the silly choice of crankset.
From the website it seems they do a SS an a tiagra geared version both using the same frame, no mention of eccentric BB.
Besides, eccentric BB systems use normal bottom bracket & cranksets. They just have rotating cups in the frame.
