Using Shimano Di2 electronic shifting technology, the ST-R8070 provides fast, accurate and effortless gear changes at the touch of a button. With no traditional mechanical shift cables to stretch, corrode or become contaminated, Di2 offers consistent shifting performance ride after ride, even in poor weather or demanding road conditions.
The ergonomic drop bar STI design places the shift buttons in a familiar position for riders used to Shimano mechanical STI levers, while the tactile buttons allow easy shifting even with cold hands or gloves. The lever is compatible with full and semi-synchronised shifting, allowing custom Di2 setup options to match your riding style and preferences.
The integrated hydraulic disc brake lever delivers strong stopping power with excellent modulation and reduced hand effort, especially from the hood position. A built-in hydraulic reservoir automatically maintains pad-to-rotor clearance as brake pads wear, helping preserve consistent braking performance over time.
With adjustable lever reach and free stroke adjustment, the Shimano Ultegra ST-R8070 left hand STI can be fine-tuned for different hand sizes, rider preferences and brake feel. Supplied without E-Tube wires, this lever includes two ports for Shimano E-Tube electric cable connection, allowing the correct wiring length to be selected for your specific bike build.
