I noticed today that there's about 3mm of horizontal free movement between my cranks and BB (hollowtech midleburns onto shimano BB).
I assumed it was the adjuster ring that had come loose and needed tightening back up to the BB, but there are no threads on the axle section that becomes visible...
Does it need more spacers or have I messed up somewhere?
I think you have not done up that ring thingy beside the crank arm. It has a small allen bolt, loosen that and you should be able to twist the ring towards the BB which should remove the gap.
