Today I noticed a sort of roughness in my drivetrain. I've cleaned, tightened and oiled (as appropriate) the pedals, crank bolts, chainring, cog and chain. No luck. It only seems to happen when I apply proper force through the drivetrain - just letting my legs spin with the cranks it doesn't really happen.
Never noticed it before - it came on quite suddenly.
I've not stripped it down to the BB yet. Reckon it could be grit or looseness in the BB somewhere?
