So that means new hubs/rim and probably heavier spokes (in addition to more of them?)
Yup. It was foolish of me to expect a stock 32 count wheel to hold up under the obscene stress 350lbs+ is going to dish out to it on a daily basis. Hopefully I can get it trued tonight and keep it going for another couple of weeks. I'm going to try and meet with the wheel guy this week and see when he can build a 40 counter for me.
