Bianchi

  

F.I.V. Edoardo Bianchi S.p.A., commonly known as  

Bianchi       ([ˈbjaŋki]) 

 is the world's oldest bicycle manufacturing company in existence, 

 having pioneered the use of equal-sized wheels with pneumatic rubber tires 

The company was founded in Italy in 1885 " 

"Bianchi pioneered the front-wheel caliper brake.  

One of his first developments was to make the front wheel smaller and use the chain invented by Frenchman Vincent to reduce pedal height. In doing so, he created a safe and modern bicycle. Compared to its predecessors, it was much easier to drive because it was easier to balance. He continued to improve the bicycle and developed a construction with wheels of almost the same size. In 1888, he made the first bicycle with Dunlop tires. 

"Bianchi bicycles are traditionally painted Celeste, a turquoise also known as Bianchi Green" 

"Examples of applications for 4130, 4140, and 4145 include structural tubing, bicycle frames, gas bottles for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages. 

 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by the United States military. These steels are also used in aircraft parts and therefore 41xx grade structural tubing is sometimes referred to as "aircraft tubing".
