Shimano is a Japanese bike brand that was founded in 1921 as a manufacturer of cycling equipment. In the 1960s, Shimano began producing its own components, which quickly gained popularity due to their quality and affordability. The brand's most famous product is the Shimano Dura-Ace groupset, which has been used by many professional cyclists, including Greg LeMond, Miguel Indurain, and Lance Armstrong. Shimano has also sponsored successful cycling teams, such as Team Sky (now INEOS Grenadiers), with whom they developed the first ever electronically-controlled shifting system, the Di2. Today, Shimano remains a leading producer of bike components and continues to innovate to meet the needs of all types of cyclists.
