Shimano was founded by Shozaburo Shimano in 1921 and started making bicycle freewheels.
In 1973 the very first Dura Ace road groupset was produced and in 1982 the first Deore XT MTB groupset was introduced.
In the 25th Anniversary year of Dura Ace 1998 Oscar Camenzind won the world championship using Shimano Dura Ace 9sp.
