back in the early 80's I tested one of the cannondale criterium type
frames (black lightening stands out). I was a whopping 140lbs dripping
wet back then (wouldn't I love to be there again).
Talk about harsh. . .
and that is one thing that has to be taken into consideration when talking
about C'Dale harshness, rider weight.
Alot of Alu frames are harsh to the sub 150 lb set, just a fact of life (imho).
