INCLUDED ELECTRIC PARTS PARTS:

ST-7970 Dual Control Lever
RD-7970 Rear Derailleur
FD-7970 Front Derailleur Braze-On
EW-7970 Electric cable - EXTERNAL CABLE SPEC  (M) 830mm or (L) 890mm
SM-BCR1 Battery Charger (110v-220v) works worldwide + Charger power cord
SM-BTR1 Rechargeable Battery
SM-EW79A-E Electric Cable

Dual Control Levers:

Similar in look to the Dura-Ace shifters but with digital shifting, simply press to change gear.

• Shifting is easy as pressing a key on a keyboard.
• Unidirectional carbon fiber brake lever blades.
• The levers themselves weigh 155g less than mechanical 7900 levers.
• Reach adjustable and compatible with the new FlightDeck computer (sc-7900).
• Titanium fixing band and bolt.
• All cables routed internally.
• Weight 255g (pair).

Rear Derailleur:

• Carbon fiber pulley cage.
• Servo driven motion rather than spring action giving identical and precise shifting.
• Built-in crash mechanism which allows movement in the event of a crash.
• Weight 225g.

Front Derailleur:

• This contains the brains of the system, the compact CPU is housed here. The front derailleur tracks the chain position and trims automatically - requires no manual trim.
• Small to big ring changes are barely detectable with a smooth pedalling input, even on a climb.
• Weight 124g.

Battery pack:

• 7.4V rechargeable lithium ion battery - easily mounted to the frame and removed for charging.
• Claimed to last up to 625 miles with frequent use, battery will hold its charge for months.
• Gives a low reading when a charge is needed.
• Weight 68g.
