Hi I ride a 2010 Focus Izalco Pro. I have had it since July and done about 1300kms road racing and crits on it. (My other bikes for reference are a 2005 Specialized SWORKS E5 and a Terry Dolan Steel frame for training/commuting).
On the Izalco I am running D-Ace7900 complete, Mavic Ksyrium ES wheels and Deda newton/Zero bars, stem, seatpost, Conti GP4000 tyres.
Enough reference points ......
I stepped off my SWORKS race bike to the Izalco. I settled on the Izalco after looking at a lot of others such as Trek, Look, Wilier, Cube. My criteria was I wanted a bike that was built in the same postcode as the brand name by a company that understands how bikes are ridden and hence built. And it had to be <7kg. The Izalco I have is 7kg on the dot.
In short I would describe the Izalco as a no fuss bike that does the job. I don't mean this in a negative way. It has a degree of stealth that lets your legs do the talking, rather than a fancy paint job. The internal cable routing looks like veins running down the tubes which looks cool.
The Izalco is stiffer than the alloy SWORKS at the BB and so I feel my leg power is better used. The ride is less compliant than the SWORKS so on rough, coarse country roads I prefer to run hand built wheels(Mavic Open Pro, DT Swiss spokes,White Industry hubs, Vittoria Open Corsa tyres) to absorb some of the road vibe. Descending is very stable, superb and direct. I am able to pick the line through corners and stick to it much better than the SWORKS. I am not a climber so basically all bikes feel pretty much the same to me going up hill. The Izalco feels efficient. In Crits I find the bike responsive and again very good in corners particularly with stiff wheels like the Mavic ESs. After riding the Izalco the SWORKS now feels soft and springy.
I think that for 2011 the higher level 2010 frames and 3T forks have migrated down the range so you get a better frame for the same money now.
If you are in Australia and can track it down the Izalco was reviewed in RIDE Cycling Review magazine JUL/AUG/SEP 2010.
Have fun getting a new bike!
