I know Parlee had some 820 gram Tri frames at interbike last month. Anybody know of others that are close?
Dave from VA
Absolute is a very tricky term of course, plus of course what the definition is of a tt/tri frame.
If light weight is your concern versus aero, we can build you a custom steep seatangle Ghisallo and that should weigh under 900 grams depending on the size. Plus of course it comes with a lifetime warranty.

Herbert,
Please email me or PM me in order for us to discuss some pertinent COPYRIGHT issues! 
Herbert, the damage is done. You better swing me some schwag or I’ll have to sue!
Their are a lot of contenders,
Ti: Ghisallo, Hollands custom
Carbon: Parlee, Calfee, Scott, Cervelo
Aluminum: Teschner, many other custom
Most of the “lightest” will not be aero tubed.
If you are actually considering buying vs fantasizing remember that fit is first, aero second and weight third as far as fastest times go. Also I would stay away from superlight if you are not in that category youself.
Finally, any superlight frame will need to be handled gently.
