The new Parlee ESX frame is out and more specs, including aero data, will be available in the next couple days.  For now I know that the weight will be mid 800 to mid 900 depending on sizing.  Obviously it’s going to be a bit more than the Z5 but surprisingly not as much as I would have thought.  Sizing is going to be more modular now.  Gone will be tall / short sizing and there will be different aero headset spacer kits for different effective head tube lengths.
