Top end triple action…
The latest addition to the range topping road groupset is theFC-7803 Hyperdrive compatible and Dual SIS (why oh why!?) Hollowtech crank arm featuring one-key release and Shimano’s superb one piece BB design.
Sensibly they have reduced the number of teeth to 52-39-30T so there is less cross over of gears and more suitable climbing/bail-out gears. Bolt Circle Diameter 130/92mm with a reinforced spider. It is available in loads of crank Arm Lengths: 165/167.5/170/172.5/175/177.5/180mm. The chain compatibility is with the Super Narrow HG for 10-speed

Short reach, at last
A new 10-speed Dual Control Lever with adjustable lever reach for riders with small hands. Reach adjust spacers of 4 and 8 degrees will be available. The ST-R700 can be used for both triple and double front drivetrain systems. We’d mentioned this before but here’s a better picture.
In case of a double front chainring, the front derailleur FD-5600 should be used. These shift/brake levers are Flight Deck compatible and they have the same ergonomic improvements as the Dura-Ace and Ultegra Dual Control Levers. The redesign allows a more comfortable position when riding with the hands on the rubber hoods. The arced shift travel makes sure that shifting is fast, smooth and ergonomic.
ST-R700 Dual Control Levers wiull be available in the market from October 2005.
