Two things stood out to me: the new Culprit aero stem (and the aero road bar looks reasonably slick too) and the continuous filament wound wheels made by Vemn (sp?).
The Culprit aero stem will be a nice addition to the market, maybe Josh can come on here and comment. I saw some prototype photos of it a while back and, IIRC, there was talk of the stem being able to hide an eTap blip box. It appears the core of the stem is made of aluminum which is something I like. Nothing against carbon fiber but my $0.02 is that it's easier for a small shop to put out a safe product in aluminum than carbon fiber.
The continuous filament wound wheels from Vemn look incredibly slick. No idea whether or not they're aero... if I had to bet I'd say they're probably on par with something from Zipp/HED from 5-6 years ago (so not bad).... but it's mind blowing to me that they can use that process to make a wheel. Should result in a much lighter, stronger, and cheaper wheel though something tells me it will be disc brake only.
