Looks like they missed the memo that everything new had to be built with discs.

I like the looks, but like prior mentions: why no integrated hydration and storage?!? That just seems baffling to come out with a bike today and not have that. It's particularly odd when you consider how much space they appear to have to work with in the top tube and the bottom bracket area.

As for aero, their website has a white paper that puts it against the P-5x in the tunnel (no rider) and on the velodrome track and they claim wins in both places.
