Not really, as you have just pointed out Bobridge has beaten the 4km time Boardman set on the same bike in the same week that he did the 56.375, so there's no technological barrier to Bobridge beating the real hour record too. Bobridge has access to technology which wasn't even invented in 1996, so it's reductive to say that the hour record will never be beaten because you can't use the Superman position any more. How far would Boardman have gone if somebody had travelled back in time and given him a 2015 skinsuit?
