The VWD is sub 1000gr... Usually around 960 depending on size n paint... The S5 team is 1200 to 1250... And base S5 model 50 to 60gr heavier at around 1300gr... There apparently isn't much difference in stiffness between the models, not that I've had any first hand experience of that... .Edit: If u refer to here http://www.bikerumor.com/2011/11/17/cervelo-s5-aero-road-bike-unboxed-weighed-and-first-rides/ It suggests base model is 1300gr, and team version 60gr less..
