I've seen several posts recently about these Chainrings. They look like a saw blade but they are cheap as hell. What is the overall consensus on these chainrings. My bike came stock with a Truvativ Touro crankset and chainring and the chainring on it is horrible. It is so far out of true its unreal. I can look down at it while riding and watch the chainring pretty much wobble. But I saw on Amazon.com the rocket rings are like $13 and that can't be too bad of a deal to at least try. So if any of you all have them, do you like it? I may go ahead and get one till I can save up some more for a nice crankset and chainring.
