Is this Vivalo worth importing...?

But Aran this is true of any bike you buy off ebay, or any other website, you never know the full true condition until you get it in your hands and start to build it up. you have to hope and trust that the bike/frame is as described, and the seller is honest with you. Whether the bike comes from tokyo or torquay its still the same situation, except you've got to pay more for the bike to come from tokyo. If you want to see and touch the bike then ebay and online purchases without personal contact probably aren't best for you.

Good luck finding the right bike for you, just enjoy riding it when you get it. ;-)

Still leaves the option of buying a Keirin frame that has already been imported and can be seen/inspected before purchase. Although choice is obviously going to be limited and it may take a while!
