That's laser cut.
4130 is industry standard in terms of cromoly tubing, and save for air hardened alloys, it's actually quite a few notches above in quality relative to what's available to make a bike frame. An overwhelming majority of name brand bike-specific steel tubesets are, in fact, 4130 in composition, and differ only in wall thickness and butt length specified by the manufacturer (this holds true wheter your frame/tubes are US, Italia, "English", or asian).
End lesson from interbike.


Someone should mention that part of the proceeds of the FBM go to the care of Stephen Murray, a badass dirtjumper who broke his neck in competition earlier this year. He has a young kid and a wife.
