Sir Bradley Wiggins will receive his Knighthood for services to cycling today at an investiture ceremony at Buckingham Palace.
Speaking after being named in the New Year's Honours List, the cyclist said: "It's quite something really.
"I never imagined that I would ever become a knight so it's an incredible honour, but there's a slight element of disbelief, and it will take a while to sink in.
"There was never any doubt whether I'd accept it or not, it was more a case that I never saw myself as a Sir, and I probably never will.
"I don't like profiting from status so it's more for my family. It's nice for my parents and grandparents to be able to say I'm a knight, and for my kids in the future."
Sir Bradley Wiggins is to be formally awarded a Knighthood today at an investiture ceremony at Buckingham Palace.

A Metropolitan Police bike safety initiative launched in the wake of a spike in the number of cyclist deaths in London will be "intensive and far-reaching"
– Superintendent Rob Revill, Safer Transport Command
Every road death is a needless tragedy that wreaks devastation on the victim's friends and family. Every serious injury is life-changing and distressing.
This operation will be intensive and far-reaching. Our aim is to reduce the appalling number of people who die or are injured on London's roads each year.
Traffic and Safer Transport officers will be out in force, and even officers who don't specialise in traffic policing will be watching and dealing accordingly with anyone they see breaking the law.
A surge in cycling deaths in London has prompted the Metropolitan Police to deploy 650 officers to the capital's busiest junctions later today.
The surge wiill see 2,500 officers will hand out leaflets and fixed penalty notices at 166 junctions marked as the capital's worst after six cyclists died in two weeks in collisions with lorries, buses, and coaches - some mere hours apart.

Our Correspondent Dan Rivers has been to Bristol to see how safe our roads are for cyclists.
The driver convicted of driving offences after she tweeted about "bloody cyclists" following a collision said she "did not think" the cyclist was injured.
Emma Way told Norwich Magistrates' Court she had lived near the road where the collision took place for 20 years and had cycled along it as a child.
Claiming the incident was cyclist Toby Hockley's fault, Way said she had been driving at 15mph and her road positioning was as far to the nearside as possible.
"Afterwards I looked in my mirror," she continued. "I did not think he was injured - if I did I would definitely have stopped."
