Shimano Ultegra ST-R8050 Shifter for Di2 Shift/Mechanical Brake
- 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.
- The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.
- Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio.
- 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.
- Programmable function of top button remote switch for third party cycle computers.
- 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 without electrical cables, as these need to be ordered separately to suit.
- For use with E-tube electric cables .
- Comes complete with SLR brake cable set.
