Ridley Noah Fast disc vs Ridley Noah Aero+ disc

[tomtom]

Hello, does anybody know what the differences between these bikes are in terms of;
- comfort
- aerodynamics
- weight(s)
I like the sleekness of the Aero + (a lot) more then that of the Fast but I can only find tests/remarks on the Fast but not on the Aero+ (also very little infor on the Ridley site). Any info/help would be more than welcome !
