Great Britain's most successful Olympic team is set to be stronger than ever at London 2012, according to British Cycling performance director Dave Brailsford and team talisman Sir Chris Hoy.

Brailsford led Britain to a haul of eight gold medals in Beijing four years' ago, with Hoy winning three of them.

There were few surprises as the team was announced at the Manchester Velodrome today, with Hoy joined by fellow Olympic champions Victoria Pendleton and Bradley Wiggins.

David Millar, who in 2004 was handed a two-year suspension for admitting use of blood booster EPO, has been included in the long list for the men's road team which will support Mark Cavendish's bid for glory on the opening day of the Games.

The final five- and four-rider men and women's road squads will be selected later this month, and if Cavendish has his way Millar will be named in the team for July 28.

But Millar's inclusion is far from certain, demonstrating the talent at Britain's disposal.

Brailsford told Press Association Sport: "There's a strength in depth that we always talk about and actually this team's got a strength in breadth.

"It is, across all disciplines, very, very competitive for the podium.

"There's a great mix, young and old. You've got the experience of the likes of Vicky, Chris and Bradley, who have been to several Games now, and then you've got the exuberance of the Laura Trotts, Dani Kings, Jess Varnishs, all bursting through on to the scene."

Hoy's first Olympic title came in Athens in 2004, but his Beijing bounty saw him become a household name and London will be his fourth Games.

The 36-year-old Scot said: "We're finally here. It's really exciting. I'm very proud to be part of this team and it really is, I believe, the strongest team we've had."

There are selection decisions still to come, particularly whether Hoy gets the nod in the sprint ahead of Jason Kenny, the Beijing silver medallist.

Brailsford's rationale for leaving Hoy and Kenny to wait is based around form and Britain have up until 48 hours before the event begins on August 4 to declare their selection.

Hoy added: "There's no point in worrying about, it's out with your control. All you can do is train hard.

"Whoever gets selected for the sprint, in particular, will do a great job, whether it's Jason or myself."

Changes to the Olympic programme and the limitation of one entrant per event mean it is highly unlikely Britain will emulate their success in Beijing, but there is medal potential across the track as proved by five gold from 10 Games events at April's World Championships in Melbourne.

"If you look at every single event, you certainly wouldn't bet against a GB gold medal," Hoy added.

"The chances of doing it in 10 events out of 10 are very slim, but it's not impossible.

"We have the possibility of winning everything we enter, but also there's no guarantee we'll win a single gold medal. That's what's exciting about sport and that's why people watch it."

Hoy and Kenny are joined in the sprint squad by 19-year-old German-born Philip Hindes, with Olympic champions Ed Clancy and Geraint Thomas in team pursuit squad alongside Steven Burke, Peter Kennaugh and Andy Tennant.

Clancy is poised to ride the omnium, with Trott in the corresponding women's event as well as the team pursuit, where she is joined by Joanna Rowsell, King and Wendy Houvenaghel.

Pendleton and Varnish are in the women's sprint squad.

Outside of the velodrome, Britain's chances are good too, with Cavendish favourite to triumph in the 250-kilometre road race which finishes on The Mall on the opening day.

Cavendish, Wiggins and Millar are joined in the provisional road squad by Steve Cummings, Chris Froome, Jeremy Hunt, Ian Stannard and Ben Swift.

If he makes the final cut, Millar will return to Olympic competition for the first time since Sydney after the British Olympic Associations bylaw banning drug cheats for life was revoked.

The main issue surrounding the women's squad to take to the road the following day is whether defending champion Nicole Cooke or Lizzie Armitstead will be leader.

Cooke, Armitstead, Katie Colclough, Sharon Laws, Lucy Martin and Emma Pooley are vying for four places on the start line.

Wiggins and Pooley are set to take one of the two time-trial places on August 1, leaving one selection still to be made.

Three-time world champion Shanaze Reade will ride in the BMX, with Liam Phillips selected despite suffering a fractured collar bone at last month's World Championships in Birmingham.

The mountain bike places have gone to Liam Killeen, who has recorded top-10 finishes at the last two Games, and Annie Last.
