Wilier was a turn of the century English company that was bought by an Italian dude in 1906 and moved to Trieste, near Slovenia. It has a long and storied history of racing in Europe, but mainly in Italy. Their website has some information on it well worth spending some time reading even if you don't want a Wilier.
I own a pair of Wilier Izoard XP's and owned a third that cracked about one year into ownership. It was replaced under warranty; no questions asked and a sincere apology was offered. Like almost every carbon frame these days, they are made in mainland China. Xpace did the mold development and layup schedules. The paint and decal work are as good as any of the top end frames...stunning accuracy and finish quality for the low price of admission.
The straight 1-1/8" steerer and headtube on the Wilier is stiff and tracks perfectly through turns. Once you're flying along it's an intuitive steering bike and input requires little thought. Just set it up, lean it over and shoot out the other side...just the way it should be.
Wilier builds some of the best racing geometry bikes on the planet and IMO the Izoard is one of them. It's dirt cheap. Competitive Cyclist sells frames and complete bikes as do several of the UK web re-resellers.
The handling is quick. It is a point-and-shoot type of steering designed to be fast for those that know how to ride a racing bike and know where they want it to go. It will get you there quickly. The BB could be a bit stiffer, but I say that about 99% of everything I throw a leg over. Otherwise it's both plenty stiff and plenty comfortable for stage racing, crits and fast club rides or training. It climbs well and like any great racing bike it just disappears underneath you. Four years on Campy Chorus equipped Izoards now and I'm still not looking for anything better.
I highly recommend the Wilier line despite that first one cracking. My main Izoard now has a bit over two years on it and it's holding up to the abuse I dish out. The Izoard lacks the latest feature such as a tapered steerer and internal cable routing/electronic group wiring capability, so think about going upmarket to a Cento (drool!) if you're into that.
I bought a TREK Emonda S Series last December for use as a winter beater training bike. I only have a few hundred miles on it due to the Ice Age we're only just now leaving behind, but initial impressions are that it is stiff. Very stiff. And I like that.
It does NOT have a low front end and I DON'T like that. I've got the bars slammed after special ordering the lowest headset top cap I could get out of FSA and they could still be 10 MM lower. The H2 fit 'may' fit a pro rider or two, but it's too tall for an aero position on the bike for even this old man with a bad back. Again, think about shopping 'down' a frame size if it takes that to get a head tube length to fit your positioning goals.
The Emonda's seat stays are stiff and it's a bit buzzy, but it scoots when you press hard on the pedals. So, pretty good in the stiff rear end department. Despite the 'S' series frame being a tad on the heavy side it climbs well...again, the stiffness is noticeable and appreciated. The overall handling is neutral. Neither a twitchy fast turner nor dead, it is just very stabile and sure footed.
Just a word on the new shimaNO 5800 105 11-speed...and I despise shimaNO stuff on general principal...it's pretty good. shimaNO pedals are good, the cheap 105 shifts well and the brakes work well. It's smooth running, the crankset is stiff (if a bit crude in the machining of the rings) and the BB86 bottom bracket is quiet (so far).
The OEM Bontrager Paradigm saddle is actually both narrow enough for my skinny ass and comfortable! Amazing! I did swap in a DEDA seatpost with 20 MM of setback to replace the OEM Bontrager 12 MM setback post.
Like I said, pay attention to little details like that when buying any bike. That was $100+ to correct a small fit difference that could not be ignored. I also installed a longer stem, but that would have been required with any off-the-rack bike/brand. Another C-Note went by-by for that.
I would buy more Wiliers in a heart beat. I don't think I would buy another Emonda without going to the top of the line SLR frame to get the H1 lower headtube fit.
I like the Raleigh Militis line, but they are on the expensive side in my area.
