I can't seem to find HED aerobars (http://hedcycling.com/aerobars/aerobar.php) anywhere (except on eBay) but I do see HED Vantage 8 (http://hedcycling.com/aerobars/vantage-eight.php) on (trisports.com).

I am interested to know what the differences are b/w the 2 bars. Other than the fact that both are at MSRP $695, I can see by the pictures that HED aerobar (699g w/ carbon ext) is a complete system, a bit heavier, and includes the brake levers and Vantage 8 (590g) does not.

Thanks!
