Componentes de bicicleta Shimano

When a single brand supplies roughly 70% of the global component market, the hierarchy runs deep. Shimano built that position through more than a century of precision manufacturing in Japan — starting with a single freewheel in 1921 and expanding into the most complete drivetrain ecosystem in cycling.

Shimano bike components at RA Cycles covers all of it: Dura-Ace 9200 and 9270 Di2 systems that dominate the Tour de France peloton, Ultegra and 105 for road riders who want pro-level function without the flagship price, GRX for gravel, and XTR and XT for the trail. Beyond groupsets: Shimano wheels, power meters, pedals, cleats, shoes, rotors, cables, and small parts across road, gravel, and mountain disciplines. Whether you’re building a complete drivetrain or tracking down a single replacement part, this is where to find it.
