Worlds lightest Fat Bike fork?

On my scales the Travers Carbon Fat Prongs weigh in at just 533g (excluding axle) No really! are they the worlds lightest? I cant find any lighter!

They feature a 15x135mm thru axle and a tapered carbon steerer tube with a rider weight limit of 110kg, that equates to 17.3 stone.

For more information check out the Fat Prong page.

Pictured below are a bunch of the thru axles...what is the collective name of a bunch of Fat Bike thru axles...Faxles?
