Actually, to appropriately describe the forces, the bicycle hangs down from the "top" of the rim when being ridden. There are some detensioning results to the forks near the "bottom", but the weight is not being held up by the bottom spokes. Actual, true vertical deformation of the rim is pretty minimal. (Tires and spokes are much more elastic) Until you hit a curb or a near-vertical obstruction. - Jim -- Jim Edgar cyclofi...@earthlink.net "One Cog - Zero Excuses" L/S T-shirt (and others!) - Now available http://www.cyclofiend.com/stuff Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Gallery updates now appear here - http://cyclofiend.blogspot.com -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
