Hey all, after my ride today I noticed some side to side play in my [url= 
]FSA Comet mega exo crank[/url] around 3mm when I press the crankset. The whole thing moves.
Not used to these new tangled BBs , any tips,on how to fix this?
NE1?
Either tighten it or replace it. Bit difficult to say from your description.
If it's only side to side play (not knackered bearings), then it's likely that your L/H crank has moved on the axle. Adjusting it is simply a case of loosening the two pinch bolts on the L/H crank, nipping up the bolt in the centre(finger tight only, otherwise you'll overload your BB bearings and destroy them pretty quickly), then re-tightening the pinch bolts evenly to 14nm (go back and forth between them after the torque wrench has clicked, as tightening one takes load off the other).As long as the crank and it's splines are undamaged, it should be fine, but will need regular checks on the pinch bolt torques, FSA use quite a narrow interface which seems quite prone to coming loose.
Thanks coatesy that's sorted it.
