About Shimano
Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
