X-treme wheels?

Anybody ridden X-treme wheels? Looks like a nice product line but I’m curious about the quality of the hubs? How about stiffness? Their Blade elite deep dish front and G-Force Elite disc look comparable to the Zipp 999 (and lighter) and about $700 cheaper but what about their hubs?

Had a pair since '98 which I just sold. Still going strong and stood up to a lot of useage over that period. No technical advice here but I never had an issue with the hubs and the wheels seemed to spin forever.

I have the G-Force Elite disc. Zipp light for less cash. Only had it for a year but no problems. Quality of carbon isn’t as good as my Mavic, but no issues with the hub. It seems more suited to the lighter rider, I’m only 70kgs. A clubmate of mine had a problem with his disc flexing, cos he’s a big powerful guy, but no problems with the hub, and the disc is still going strong. His trispoke front has had no issues.
