Just wondering if you guys have had problems w/ breaking wheel hubs on the Genesis. I have broken them every way possible and I was looking for an upgrade. I saw CEN had a "Universal Upgrade" MXS13 aluminum wheel hub, $79 a pair. I may be wrong but Im sure "Universal" doesnt include everything from a Fun Factor to the new Nemesis does it. Other than New Era or HardCore Racing who else makes aluminum or titanium for the Genesis. Thanks in advance for your help!!!
