The crank arm fixing bolt that holds my cranks on the bike loosened on me today. I noticed it after my crank arm moved out from the BB about 1/2 inch! I tightened it as much as I could. After another 8 miles, it was loose again! AAAARRRRRGHHHHH! Another cyclist told me that FSA cranks were known for that. Bummer if its true.
Anyone know how to fix it?????????
