Just purchased a rockin' Trek Top Fuel 69er. The thing just rocks! I have a set of Mavic 819's w/ King hub's from my old bike that I would at lease like to use the hubs. As far as I can tell from their wesite, Mavic doesn't make a rim for a 29er unless you go w/ the C29 ssmax & I personally don't think the Mavic hubs are near as good as the Kings. Does anyone know of a lite/strong rim that comes in a 26' and 29' that I could use w/ my King's? I'm wanting to build the bike up lite, but still needs to be able to handle the rocks & roots of the Ozarks. Help please!!!!!
