Before the wheels swap the bike (Ribble Sportive Bianco, Athena groupset, Khamsin wheels with Gatorskin Hardshell tyres) weighed in at 8.88Kgs but after the swap to Zondas/Ultremos the weight was 8.04Kgs, a much bigger saving than I expected. The 0.84Kgs difference is really noticeable, although I'm still not 'flying up the hills'. That's just me though.
The Zondas seem to be Campagnolo's best kept secret. They're lighter than Neutrons.
PS Get them from your local bike shop if you can, but if not, they can normally be bought in the back of Cycling Weekly magazine for £274 - which has got to be one of the bargains of the year. You should find them elsewhere for under £300.00. I'm sure your LBS will try to match that price if they can.
*Update* I switched the Zondas to my Tifosi CK7 Veloce (winter bike) when I sold the Ribble. Even with Gatorskin Hardshells they still ride very nicely, and I've had no issues with them at all. They haven't needed truing, the spokes are still fine and the hubs still roll smoothly 18 months later.
