original s6,  Tuesday, 05 August 2008 if pumping and flatland cruising are you disciplines, you wont be unhappy. i wouldnt recommend them over 30mph unless you get bigger wheels and a stiffer spring. the bushings are plastic and the way the thing is designed means that you have to keep those moving parts greased with lithium grease to keep them from destroying their life. slightly annoying fact that the bushing do have to be replaced ever 12 months or so. but the trucks really are just so smooth in and out of every transition and turn.
