|Hi my sponser is selling my current ride(a connondale cadd5) and putting me on a Giant TCR0 for the next season. My question is what is the weight/ aero benefits of one of the Giant seatposts. Have there been any figures thrown around? I was thinking of using a USE alien seatpost instead.|

|they're heavy in the same range as generic low end alloy SP. I have one and like it but I was too lazy to drop it on scale.
With respect to aero benefits I haven't seen much info. Wheels generate ~2-3% drag, so SP must be ~0.3% (?) not comparible to skinsuit. Still aero probably outweights extra 100g of weight.
btw USE makes aero SP should be lighter hey if your sponsor pays for it ;)

In it John Cobb talks about aero seatposts and what the thinks of them, from an aerodynamic point of view, it might be of some help to you.
