BALLS!!!! So i followed the advice from all you helpful people, and borrowed a chainwhip and bought a lockring doohickie. Tightened the **** out of the cog (first with chain whip then rotafixed it just to be sure, also was careful not to apply "excessive force" as the website suggests)... moved on to lockring and tightened the **** outta that. I run a front brake so i rode around for a few blocks without back pedaling just to be sure. Do a few skids followed by fast accelerations from stops just to run it through its paces and everything seems fine.

I'm out riding last night, on my way home, and have to perform lots of little skips and such as i'm riding with skateboarders and gotta show off a little ;-) anyway... long story short... STRIPED THE F*CKER!!!! BALLS!!!! I think this must be due to damage incurred from not being tight after the original build (which i had done professionally to avoid something like this). Is this my fault? Did I kill my baby?

Steve - off for some sweet sweet warantee work :-)... followed by a close inspection on my part with all the knowledge you guys have given me - Thanks
