I had a big ride last Sunday. Before hand, I noticed that my chain was not as tight as I'd like, but figured I'd get through it and deal later. But, after the ride (some big declines that required lots of skids) I noticed that my chain was REAL tight. So I went to my LBS today to see what's up with that. I thought the force on my slowing was pulling my rear wheel back on the drop outs that resulted in tightening the chain, but my boy at the shop said I may have bent my chain ring making it slightly oval, and not round anymore. Is that possible? I run brake-less, and only stop via skip/skids. I'm 6'1 190lbs. Just wondering.....now I need a new chain ring cause it's totally noticeable. All good tho, cause I found a sick anodized Pake 46t 170mm for $60 on ebay, but do I need a better/stronger chain ring?
