Smooth, crisp and silky shifting, the Shimano Ultegra R8050 Di2 11-Speed Front Derailleur is an addition that will give you the ultimate riding experience.Top Gear Teeth: 46-53TChain Line: 43,5Braze-On ClampWeight: 132gVastly improved performance over mechanical shifters due to electronic front derailleurs' lack of susceptibility to cable stretch, this Ultegra Di2 compatible component uses electronic shifting cables to move a measured amount each and every time, regardless of conditions or environment. With millimeter accurate shifting guaranteed time after time. Compatible with Shimano's Syncronized Shift technology, this derailleur is intelligently designed, and, with your input, can be programmed to shift in order to maintain optimal gear ratios automatically. Redesigned to fit wider gear pitch, this front derailleur can take chainrings sized up to 53 teeth and go as low as 46 teeth, assuring you of a smooth transmission when switching between the two. Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available
The SRAM X1 rear derailleur shares all of the same great technology as the more expensive X01 model but instead features an aluminium cage instead of carbon which adds a few more grams but also keeps the price down! Every detail of the 11-speed X1 X-Horizon rear derailleur is engineered for smooth, reliable shifting action-from the larger upper pulley offset to the 12-tooth X-SYNC pulley wheels. By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever. Roller Bearing Clutch rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain. With Roller Bearing Clutch technology, derailleur bounce and chain slap are eliminated without sacrificing precision.
The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur 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 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 Designed to work with the wider gear pitch spacing Shimano chainsets without sacrificing shifting performance on bikes with 135 / 142 mm O.L.D. Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available 12-speed E-tube SD300 wire compatible
