With the new Ultegra R8050 rear derailleur 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 not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.Compatible with 11-speed Di2 systems, this derailleur is made from high tolerance cold forged aluminium for incredible durability and a longer lifespan. Benefiting from a low-profile shadow design construction that reduces the risk of damage in the event of a crash, this derailleur also remains more aerodynamic on the bike, sitting poised and perfectly placed to flick between your preferred gear. A low friction shifting action guaranteed by four self-lubricating micro-machined fluorine coated link pivot bushings, you can be sure of joy each time you switch your gear.Low profile shadow design constructionHigh tolerance cold forged aluminium link platesSS Cage: Compatible with 11-25T Up To 11-30TGS Cage: Compatible with 11-28T Up To 11-34TWeight: 242g (SS Type), 249g (GS Type)

Shimano Di2 electronic shifting lets you change from the big to small chainrings, or vice versa, whenever you like while minimising the risk of a dropped chain. Similarly, you can perform rear shifts without the need to trim the front derailleur to avoid chain rub. Full- and semi-synchronized shifting functions can be selected using the E-TUBE app. With digitally accurate electronic shifts and coordinated communication between shifters and derailleurs, the new Shimano 105 front derailleur offers the best shifting you've ever experienced.Great value high performance 105 double Di2 front derailleurThe Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to wireless communication with the gear levers.
