Hi, I have recently, 4 days ago, acquired a 2010 South African made Epic V10 Sport. Set aside the "quality" debate, is there a physical difference in the RSA mould vs the Chinese mould? I am NOT referring to the new 2014 shape, I am referring to the previous shape. I was told that the seating position is higher in the RSA mould and that would make the Chinese model more stable...
