Shimano’s new and improved website has details of the latest launches, including the Dura-Ace triple and the short reach stuff. Check back tomorrow for the pictures of the new and improved 105…
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.
