In the last few months, I've managed to break a spoke, and decided to ride on it anyway (Because at the time, I had no idea how to fix it.) I kept riding on it until I broke the axle. (It snapped in two) and decided now is as good a time as any to fix it. The problem is, Alot of the spokes seem to have very little tension. I can wiggle some of them, and some are tight. Could this have been caused by me riding with broken spokes? Is it repairable?
