Hold your horses @ProRaceMechanic is currently selling a pair of Zip wheels at bargain price 80,000 and they are virtually new. He is a Mechanic for a Japanese Pro Team so often has hardly used kit for sale and as a erm Pro Race Mechanic that also worked for Mavic you can be pretty sure the wheels are in tip top condition.
Just noticed @FarEast 's post about @ProRaceMechanic 's zipps for sale. I'd definitely have a look at those if I were you. I've only met the guy once but he is a top guy.I had ridden out to Nagano with another member of this forum. One of my spokes decided it didn't want to leave Saitama so it jumped ship and I was left with a very wobbly wheel and 3 days of riding to come. A quick call to @ProRaceMechanic and he met us with a spare front wheel (a fancy linited edition mavic ksyrium) and let me borrow it for the remaining time in Nagano. Sure you can't go wrong getting a set of wheels from him.
Zipps are distributed in Japan by Dirtfreak . Jus check their website what's available. Some models are not released in Japan. So, if you want those in particular , then order offshore. Almost any LBS can order from Dirtfreak ,btw, once they have valid acct set up. This goes for SRAM and other parts as well. DF are cool folks. Roll with it.
