Shimano Ultegra ST-R8150 Di2 Mechanical Lever Left STR8150L

Shimano Ultegra ST-R8150 Di2 Mechanical Lever Left Shimano’s Ultegra ST-R8150 Di2 Mechanical Lever Left combines 12-speed electric shifting with rim braking - perfect for riders who wish to upgrade their non-disc bike to Di2.  The Servo Wave brake lever is designed to be used in conjunction with Super SLR brake calipers to provide power and modulation for confidence-inspiring control on fast, twisty descents. Reach to the lever can be easily adjusted so that all hand sizes can be accommodated and the ergonomic levers fit neatly under the fingers. Sprocket changes are accomplished incredibly swiftly with just a light press on the lever, and lever functions can be personalised using the E-Tube app. The app will also select full or semi synchronised shifting modes, which add a degree of autonomy to the system, simplifying gear changes and ensuring that an appropriate cadence is maintained at all times. This mechanical version of the shifter needs to be wired into the battery and derailleurs to work.
