Hi, I just bought a Cr-Mo bike, parts are Shimano XTR M900, selle italia, Itm stem. The fork is 1"made of aluminium and weights 630gram. Frame is 1.9kg. The red paint is not original, the original is blue metalic. Now i"m removing the red paint, but it's just a bare frame. Ritchey drop outs. The serial number is stamped on right of the top tube: IL 42-00133/sf. Total weigh is 10kg. Who made my bike? Thank's.
