Shimano Ultegra Di2 STI ST-R8150 Right-Hand Shifter – 12-Speed, Drop Bar (No E-Tube Wires)

The Shimano Ultegra Di2 STI ST-R8150 delivers precise, effortless shifting and exceptional braking ergonomics for road cyclists. Engineered with advanced Di2 technology, this right-hand 12-speed shifter offers seamless gear changes with just a light touch (akin to clicking a mouse) providing accuracy and reliability for every ride.

  • Di2 Technology: Experience precise, instantaneous shifting for both front and rear derailleurs with minimal effort.
  • Customisable Synchro Shifting: Full and semi-synchronized shifting allows you to programme and fine-tune gear changes. A single shifter can control both front and rear derailleurs, with semi-synchronised shifting automatically adjusting the rear derailleur after a front shift for optimal gear ratios.
  • Tactile Button Design: Effortless shifting is guaranteed, even with cold hands, thanks to the thoughtfully placed and responsive buttons.
  • Drop Bar Ergonomics: Shift buttons are located where you would naturally expect, mirroring the positioning of mechanical Shimano STI levers for intuitive use.
  • Servo Wave Brake Lever: Optimised for use with Super SLR brake calipers, delivering increased braking power and exceptional ergonomics while riding on the hoods.
  • Adjustable Fit: Finely tunable reach adjusters ensure a perfect fit for all hand sizes.
  • Wired Connectivity: Compatible with SD300 series wires for reliable connections to front and rear derailleurs.

Whether you're a competitive racer or an enthusiast, the Shimano Ultegra Di2 STI ST-R8150 Right-Hand Shifter delivers cutting-edge performance, effortless gear changes, and a fully customisable riding experience.
