If you think you can
Hope that's not a stupid question. But when I had these built up, I thought I couldn't go wrong. But in a few months, I have beat the hell out of the rear rim. It has flat spotted in a few places, it's been trued several times, there are even two small cracks starting at two of the spoke eyelets! Would 729's be any stronger? The guy who built them seemed amazed that the spokes were loose after the first month. He re-tensioned them, but it just got worse. I need help!
