I have an older FSA SLK crankset, and the bolt has always been a problem. No matter how hard I try it just wouldn't stay tight. Well today on my way home from a fifty mile ride it had come loose for the second time today, and I had tightened it before I left too. This time though when I tightened it it suddenly started turning free, but what had actually happened was that the flange sheared off, making the bolt useless. I took the long silver sag wagon the rest of the way home.
My question is whether I did any damage beyond the bolt? I already ordered a new bolt and extractor set from FSA but will I still have problems?
