Yeah I guess all that would make sense. I just wouldn't think my riding is aggressive enough to do that. The first one was prob that way when i bought the machine (at least I assumed) but after my ride this weekend I can't believe the other side broke too. I guess it's better than breaking an axle since these are cheaper and a lot easier to replace but still kind of disappointing. O well at least it's not just me, thanks for the replies.
