Cleaning off my workbench and I found this thing. Looks almost like a shark fin chain deflector from the late 1980s.
It's very light, seems to be pure carbon fiber, no metal in it. There are two small bolts with it.
Anyone have any idea what this is? https://uploads.tapatalk-cdn.com/202...f23f9465a2.jpghttps://uploads.tapatalk-cdn.com/202...675141f54b.jpghttps://uploads.tapatalk-cdn.com/202...6d34642ff7.jpghttps://uploads.tapatalk-cdn.com/202...5686ca8e9e.jpg
