Are you breaking the rim itself, as in cracking? Or is the hex stripping? If the later the 23mm dace adapter helps to resolve this issue. In addition to the 40 series 23mm wheels proline has recently made the 23mm wheels in the standar size velocity series, currently in a 1/2" offset and standard max offset. Depending on your tire wheel combo, the 40 series will offer greater ground clearence, contact patch, trac width, and more weight than the standard. The standard velo's are not bling bling where as some of the 40's are.Many love the RPM wheels, the material used though appears to be somewhat soft / flexible, they do take a beating, but the smaller hexes tend to deform or strip when used with high torque motors. I have never owned aluminum wheels. My concern however would be weight. Love the Bling Bling though of the ones that UE/Supermaxx offers. Mike ought to be able to hook you up with some if you choose.
