Wanted to have electronic shifting due to arthritis and this fitted perfectly. Not much more expensive than Chinese alternative and got great price from Sigma. Great deal

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.
