  • Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
  • Drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI
  • Brake lever pivot is positioned to be used with super SLR brake callipers, increase power providing excellent ergonomics when riding on the hoods
  • Finely tuneable reach adjusters for the levers enable custom fitment for all hands
  • Levers are supplied with electrical cables

Ultegra Rear Derailleur

  • With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • 11-32T wide gear ratio capacity will cater for compact setups as well as the traditional road double
  • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
  • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
  • 11-speed E-tube Di2 compatible

Ultegra Front Derailleur (BSA threaded english standard)

  • The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur
  • The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load
  • The difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggering
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
  • The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead
  • Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
  • 11-speed E-tube Di2 compatible
  • Weight: 162g
