No not track wheels.
Actually for the price (and weight) they are probably bomb proof! Weight is not necessarily the most important issue with aero wheels, my Mavic Cosmic Elite's come in at 2kg.
It could be the hubs are the heaviest bit of the wheel. It looks like the hubs are made from weapons grade steel which wouldn't 'necessarily' make them bad.
Why they have weighed them with the skewers I don't know, considering nobody else does (and they aren't in the picture).
Get them and do a test for us!
Actually....What is your budget? I could point you in a direction...
