Shimano components
Shimano was founded in 1921 in Sakai, Japan — a city with a 600-year tradition of precision metalworking — and has spent the past century building the case that bicycle components work best when designed as a system. The company began as a freewheel manufacturer and spent the following decades expanding its engineering scope across the entire drivetrain. In 1973, Shimano launched Dura-Ace, its first complete component group, establishing the system integration philosophy that defines the brand today: derailleurs, shifters, brakes, and chainrings engineered to work together. That philosophy has carried Shimano to the top of professional cycling, where Dura-Ace Di2 has become the drivetrain of choice for riders who demand precision at the highest level. The RA Cycles Shimano collection covers 665 products across road, gravel, and mountain — from flagship Dura-Ace R9200 to everyday accessories, pedals, shoes, and wheels.
