I'm having problems with my crank/spindle coming loose. I've replaced the bearing's and tightened it all a while ago but it keeps coming loose and then making my chain come loose too. Does anyone else have this problem and also is there any way of solving/fixing this ..... thanks

-Splines are wearing out & causing your crank arms to wiggle around & come loose
-Not enough spacers so the spindle is going too far through the arm & not being able to be tightened
-Too many spacers so the arm isn't on the spindle enough & keeps coming loose
-You don't have your internal spacer in your BB installed, this will cause your cranks to come loose
-Bolt/spindle threads are stripped
