Abbotsford Cycles now has NuVinci hubs in stock. The hubs retail for $590 including controller, cog and disc brake mount (if required). For more info see the NuVinci hubs website.
The NuVinci hub uses a non-traditional internal system of tilting ball bearings to make gear changing smooth and ensure there are no gaps in the gears. For more information see the NuVinci website.
