Is the rim brake track still in tact on the new super 9 like it was on the older version even for the disc brake version? It’s had to discern from the pictures.

I think this version is a little more expensive than its predecessor. Maybe $100-200 more.

Is there any aero data that can show the delta between the older (25mm optimized) vs newer (28mm optimized)?

Edit: Is this the first hookless disc? I’m a little surprised zipp came out with one before enve.
