CAAD10 105 at £999, its a no brainer IMO. Seriously, the lightest most advanced aluminium production frame to date, with a race ready groupset, probably comes in at less than 8kg with the stock wheels, this thing will probably exceed most manufacturers £2k carbon machines, assuming it fits you right (however not sure if the CAAD10 is as harsh as the CAAD9, but you might want to save an extra £100 for a carbon seatpost to save your arse

).
I'm well on my way to becoming Cannondale loyal though, so bare that in mind when considering my opinion

i.e. treat it with some healthy skepticism
Rob speaks very wisely indeed

Some doom mongers criticise the thin tubing of the CAAD10 saying it dents too easily, however when some knob knocked mine over into a railing on the Manchester to Blackpool this year the top tube merely got scuffed, despite hitting the rail square on it hasn't dented in the slightest, so that rumour is well and truly squashed.
My bike weighs in at 16.5 lbs, (7.5 kg). Granted it's now full DA, (changed the front mech and calipers), the wheels are Mavic Ksyrium SL's, and the finishing kit is full Ritchey WCS alu, but even the stock 105 won't be much more I wouldn't have thought.
As far as harsh goes I don't think it is. The longest single ride to date has been the Manchester to Blackpool where I clocked 62 miles, and I was actually fresher off the bike than I was 12 months earlier on the Focus Cayo Pro I used to own.
The 105 comes with a carbon wrapped seat post, so perhaps that would be ok. My CAAD DA came with a full carbon seat post, (Cannondale C2), that was the first thing I changed. Replaced it with a Ritchey WCS alu post, (my preference as I'm anti-carbon, chainset will be changed to DA when funds allow).
I always wanted a Cannondale even when I used to ride MTB's, and now I have one I'm very, very happy with it. Supply can be a bit hit and miss, so I'd strongly urge that if you like the CAAD10, and you can source one in your size don't think about it too long, grab it while you can. My CAAD in a 60 frame was the last one in the country at the time, I dread to think how long I might have had to wait if I'd had to order it.
I appreciate Wheelbase in Kendal would be a bit of a trek from Birmingham, but it was the best bike buying experience I've ever had, (and only an hour away for me). The staff are knowledgeable, enthused and friendly. They are all bikers themselves and can give advice sourced from both their own experiences and that of the Wheelbase racing team. So if you fancy a day out in the Lake District I would recommend Wheelbase to you without any reservations.
