Worlds Fastest Shifting Chainrings!

That’s a bold claim!  With some cool technology and a lot of racing experience to back it up.  Have a look at the business side (shifting side) of the chainrings in the pictures on this page, and note the special ramps.  Those are not little bumps . . . Not single-point-of-contact pins . . . Instead, WickWerks ramps are dramatic, full-size, chain grabbers.
