Chris Hoy moved a step closer to a hat-trick of gold medals after coming through his semi-final against Mickael Bourgain of France.
The 32-year-old from Edinburgh was hardly troubled by Bourgain and Hoy won the best of three series in straight races.
Hoy and Bradley Wiggins - who races later in the Madison in partnership with Mark Cavendish - are both seeking to become the first Britons in 100 years to win three Olympic golds at the same Games.
He will meet Great Britain team-mate Jason Kenny in the final and the 20-year-old Lancastrian looked in fine form as he also came through his semi in straight races, against Germany's Maximilian Levy.
In the women's sprint, Victoria Pendleton advanced to the gold medal final.
The 27-year-old from Hitchin saw off the challenge of Holland's Willy Kanis in some comfort.
