For some bizarre reason the most comfortable ring of my CB6000 (the slightly larger than middle one) broke last night. This was REALLY bad. I had only just explained to my wife about my CB and she had accepted it. She let me wear it all night. But this morning the hole had split. I wouldn't trust superglue as it's unreliable under stress so I changed to the smaller ring which REALLY pinched even though I perservered all day. I'm now in the largest ring but it's too loose. Is there a supplier in the UK who sells just the rings? Alternatively is there a kind soul who wants to swap.
