Product Details
Shimano Ultegra ST-R8150 Di2 Mechanical LeverOffering 12-speed electronic shifting for riders who prefer a rim brake, Shimano’s Ultegra ST-R8150 Di2 Mechanical Lever provides effortless, accurate gear changes and reliable stopping power. Designed to be used with Super SLR brake rim calipers, power and modulation are available in abundance and the reach can be fine-tuned to suit all hand sizes. Shifting is as easy as pressing a button, with the lever functions able to be programmed via the E-Tube app to perform in a variety of configurations. The app can also be used to select full or semi synchronised shifting modes, where certain sprocket changes occur automatically to maintain an ideal cadence. The system uses a single, internally mounted battery (not included) and wired connections for fantastic speed and reliability. |

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.
