I hope you get on with this bike and it loses it's sluggish feeling.
I see one of your other bikes is a blue Ribble - this might be the main problem. There's often lots of criticism on here about the Ribble Audax, whether it's about the clearances being a bit tight for mudguards, the ride being uncomfortably stiff or the position being too aggressive. Despite these, or maybe because of these, when set up well they're a really fast bike imho. Your new bike has got a lot to live up to.
