Shimano Ultegra ST-R8150 Di2 Mechanical Lever Right
Offering 12-speed electronic shifting for riders who prefer a rim brake, Shimano’s Ultegra ST-R8150 Di2 Mechanical Lever Right 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.
