Most framebuilders that work with steel have ignored the newer integrated headset design. I belive that it is the future. I decided to make up some very special head tubes for my bike projects.

Stock

The 4130 stock required for this part is very rare. 1.750 OD x .250 Wall.

I ended up ordering the stock from Factory Steel and Metal Supply Co. out of Detroit, MI.

The price was $18.70 per foot with a $20 cut charge from 20 foot lengths. A six foot section should be enough to get 14 x 4.5" tubes.
