the RD may be broken...not sure. otherwise it's fine. Yeah, like everyone else said. Try a little mountain biking. Those little scratches are normal for a light ride in the woods. and dirt makes the wounds look cooler.
example of how dirt makes injuries look cooler...caught handlebar on a 18" dia tree. Went over the bars and caught my leg on the tree when flying through the air. Very minor tangle...Only broke my headlight mount. Before and after a shower...
