Sir Chris Hoy said he is stepping down today because it is time to let a younger rider shine.
He told reporters: "Nothing would have given me more pleasure than to continue on for another year, to be there in Glasgow to represent Scotland, to be part of the team.
"But I just feel that I don't want to be there just to make up the numbers I want to be there to be competitive and being objective about it I realise I got everything out in London, so I think it would be better to let a younger rider come through to give them chance to shine."
