    Problem. Crank moving side to side. Fly Pro

    I have about a quarter inch of play in my bb. It is enough that it is hard to shift to the big chain ring. The bottom bracket appears to be tight. I havent put a wrench on it because im not familiar with these new fangled style bbs. My bike is a 2011 Fly pro 30 speed dyna sys with fsa v-drive cranks. I emailed bd in search for a remedy. Im waiting for a response. If it is something easy I can fix that would be great. Thanks in advance for any help.

    Did it always have play or is it a recent development?

    It is a recent problem. After poking around a little I found the problem. The hex bolts came loose and Tue crank was sliding off of the spindle. I squeezed it back together and tightened it. Should I put lock tite on those bolts to prevent future loosening?

    I had the Sam issue with my fly pro ds. I torques the bolts and haven't had the problem since.

    Proper torque and loctite go a long way.
