• Hollowtech II integrated
• English thread
• Weight: 77g

• 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

• Di2 charger for the internal battery that will keep your Di2 system shifting
• Di2 uses a powerful long-life 7.4V Li-Ion battery: keep it in top condition and ready for shifting with this specific Shimano Di2 charger
• 1.5 hour charge time
• Plugs in directly to the SM-EW90 handlebar junction A (Included with this groupset)
• Can also be used for completing firmware updates when linked to E-tube software on your PC

• The power house of Shimano Di2 is a long-life 7.4V Li-Ion battery that is both compact and reliable, taking shifting effort away from you
• Excellent sealing and reliability have been proven through repeated field tests in various riding conditions, including extreme temperatures, rain, mud, and cobble stone roads
• Using a hard wired battery system which is both light weight and accurate compared to current wireless technology (as a wireless system would require 4 batteries: one for the RD, one for the FD, and one for each shift lever)
• The use of a single small and discreet internal battery is light weight, efficient and creates a robust and reliable system
• One charge can give between 1000 and 2000 kilometre range depending on conditions and front mech operation (as this is the main power drain)
• 500 times rechargeable life
• Internal chip enables system wireless functionality of Bluetooth components
• Battery is to be mounted with seatpost or frame/fork manufactures hardware normally inside the seatpost or seat tube/fork steerer
• Reliable and secure water resistant E-tube terminals connection
• Charging is done via stem junction or handlebar display
• Battery weight is 50 grams
