This 50cm CAAD10 frame (no fork, but with the BB30 bottom bracket installed) weighs 2.8lbs (1270g). I weighed it with a baggage scale, so it's not the most accurate weight, but I think it's correct within .05lbs. So the precise weight is between 2.75-2.85 lbs (or between 1247-1292 grams).
It feels light and stiff for sure. Interesting to see the interior and how the tubes were placed together.
