This web site is slightly mysterious. It appears to be a full-blown, professional web site, offering a full-blown, professional range of products, including the Vivo V5 derailleur. This looks to be a nicely made, if slightly conventional product.
The one fly in the ointment is that I don't know if any of these products ever made it to market. I certainly never saw them. But perhaps it all happened online or in a discrete booth hidden in one of the darker corners of Interbike.
