I found this somewhere in the net while searching what the hell is Cro-Moly.

"Specifically, 4130 steel - an alloy steel - which is commonly known in the bike industry as chrome-moly, contains the following alloying agents: 0.28- to 0.33-percent carbon, 0.4- to" 0.6-percent manganese, 0.8- to 1.1-percent cromium, 0.15- to 0.25-percent molybdenum, 0.04-percent phosphorous, 0.04-percent sulfur, and 0.2- to 0.35-percent silicon. The other 95-plus percent is made up of good old-fashioned iron. Now, there are hundreds of kinds of steel, but 4130 finds its way into bike frames because, among other attributes, of its weldability, formability, strength, ductility and toughness. (Many low-buck frames are made with 1020 steel, which is called plain carbon steel, and has significantly lower strength than the chromium-molybdenum steels.)"

Now that what my bike is made of. Just slightly better than basikal 7-up kampung tu. Hahah!
Neway, basikal aku belum siap tranfer enjin lagi. Should be ready by tomorrow.
