Shimano bike components: the latest reviews, news and buying advice

Shimano is one of the world's biggest component manufacturers and has been producing bike components for almost a century. As one of the ‘big three’ drivetrain component manufacturers (the other two being SRAM and Campagnolo), Shimano groupsets and parts are always well-made, usually well-regarded and often well-priced. 

If you’re looking for the latest news and reviews of Shimano products, this is where you need to look.

A brief history of Shimano

Shimano was founded in Japan in 1921. The brand began life as Shimano Iron Works, producing innovative components that helped shape bikes into the machines that we know and love today.

It’s directly contributed to some of cycling’s biggest innovations, including indexed shifting, dual-pivot brakes and integrated shifting, among many others.

While Shimano also manufactures a multitude of other components, including handlebars, stems and seatposts (primarily under its PRO sub-brand), as well as clothing, eyewear, bags and footwear, Shimano is best known for its road and mountain bike groupsets.

Shimano now offers electronic Di2 shifting in its top-end road (Dura-Ace/Ultegra) and mountain bike (XTR and XT) groupsets, and in the past few years has also added hydraulic disc brakes to its higher-end road groupsets.

The company produces a wide range of groupsets across all disciplines.
