Ok, so I searched the forums and google as well and haven't been able to find an answer as of yet. Maybe I wasn't using the right words. The problem is that my crank just wont turn when I tighten down the arm bolts. It takes excessive force to get it to turn at all. I'm just tryin to figure out what's causein the problem so I know what i'll need to order. Any help would be greatly appreciated! They're the Poverty POW by the way.
