The future of shifting technology is finally available to us common folks. While Shimano's top-of-the-line XTR Di2 electric shift levers were amazing, they also came along with a pretty hefty price tag of $250 each. Now, you can get a Shimano Di2 shifter for less than half of that, without sacrificing the buttery-smooth shifting that made the XTR so awesome. Yes, trickle-down technology is a great thing! Now that the excellent (and affordable) Shimano XT Di2 8050 Shift Lever is available, you can expect to see electronic shifting becoming the norm rather than the exception.
Thanks to the 8050 Lever's Synchronized Shifting feature, front derailleur shifts can be initiated by the rear shifter. As the limits of the cassette are approached, the onboard computer will choose the best gear combination according to chain line and power output, and if that requires shifting the front derailleur, your robot drivetrain will do that. All you have to do is pedal; no front shifter required. Easy, automated, and efficient—this really is the future!
As demonstrated on Shimano's Di2 road groups, electronic-assist enables enhanced ergonomics and less effort at the levers, which 8050 Di2 provides also. Using a push-push design, each shift lever follows the natural arc of your hand, and the circular clamp design allows optimal positioning for every rider's unique physiology.
Remember, Shimano's left/front Di2 8050 shifter is not necessary to successfully run a 2X or 3X drivetrain. Syncro Shift allows front and rear shifting from the rear shifter only; the computer determines when to shift the front derailleur. This feature can be overridden for manual front shifting, which does require the use of a left/front shifter.
