I own a [insert bike model] - its a fantastic bike with some caveats.
it is extraordinarily fast. it handles and brakes really well. it looks fantastic. in my view ( and feedback from clubmates say as well) , its faster than an equivalent [insert bike model] (though that may have something to do with the engine on top), its far more compliant than a [insert bike model], and looks better than the out going [insert bike model] (subjective view). i've back to backed it with a clubmates [insert bike model], and it rides better (but i'm biased!), though doesn't climb quite as well.
Negatives: adjusting anything is a pain and requires you to carry extra's like spacers for the brakes ( if you run zipps or carbon based wheels) for when the pads get worn as the brakes don't adjust like conventional rim brakes ( they are mini vees). the salddle adjustment needs a 13mm spanner. adjustin the seat vertically needs 3 pairs of hands!
I haven't tried it against many other aero road bikes.
Impressive amount of words used to say nothing.
