I'm in the process of building up a single-speed dirt jump/street bike and the only part(s) I'm hung up on are the wheels. First of all, are 36h rims that much stronger than 32h rims? Secondly, I'm having trouble deciding on hub/rim combos. I'm currently looking at a Hope Pro II SS rear hub and Pro II 20mm front hub laced to either Mavic EX 721s or Sun MTXs. I'm also thinking about using a DMR Revolver SS rear hub to save some money. Any suggestions? I'm fairly new to the dirt jump riding, but I ride about 3 times a week at Ray's Indoor MTB Park and am quickly progressing. Any help you can provide would be greatly appreciated. Thanks!
