My girlfriend has just got one of these 650c cannondales. the black one with pink flames on it. one of the best paint themes i've seen. will post pic as soon as i get a digi camera. here's the spec anyway, don't have scales but would love to here what anyone thinks of it and estimated weight.
cannondale frame 47cm. with alloy steerer si slice fork
full 04 record group with the carbon cranks 170mm, 11-23, campag cables
deda newton stem 100m deda 215 bars 42cm
use alien post 270mm
look jaja pedals
exustar carbon cage
campag hiddenset..not the carbon top cap one
wheels are just velocity training ones
waiting to get either zipp 303's or about to bid on some 650c ada's on ebay.
also 650c wheels are actually less aerodynamic than 700c wheels. quoted from john cobb. aero guru. stiffer lighter and xlr8 better though and make for a much better handling bike for small sizes
