I have ridden MX bike's for the last 16 years and always seem to get dents in the outer lip of my rims. I'm finally going to spend the money and buy myself some aftermarket rims in hope that they don't dent as easily as the stock rims. Which aftermarket rims are the strongest and least likely to get bad dents? I have been looking at: Pro Wheel, Excel, and D.I.D. Anyone have suggestions? I run my tire pressure at 15lbs in the trails so I don't think tire pressure is the problem... I just ride fast (5th gear a lot) and occasionally hit a rock or two that are unavoidable. I do desert races too and there is no way to ALWAYS take a smooth line.
