I just bought this Truvativ chainring guard. I doesn't come with any instructions or anything and I'm really new to wrenching. My experience is limited to seats, handlebars and stems, and (very recently) overhauling pedals. My bike has a FSA Vero single 46T crankset. Just looking at it I think I might need longer bolts, but I'm not sure. I don't really want to start this project until I have an idea of what to do! Can someone kinda walk me through what I need to do to install it? What tools do I need? Or, would you say this a little above my head and I should take it into my LBS? Thanks for any suggestions you might offer.
