1st one lasted me two weeks, killed it on a drop gap at the end of a comp. second one stayed intact, but the spokes would just loosen for fun, so I took it off. I went and played with my dented one, I sat on it in my room and snapped it in half, I could then snap the halfs into quarters by hand, I have never been able to do that with a rim before! Also, the sidewalls are just as thick as normal rims, at least mine were. How is everyone telling how thick they are? you cant just look down from above as the bead hook blocks the view. anyway, they are the worst rims I have ever used
