Steve Cummings (Dimension Data) has been called up to the British cycling team for the Olympic road races in Rio after Peter Kennaugh failed to recover in time from a broken collarbone.
British Cycling confirmed the change on Tuesday, saying the 27-year-old Kennaugh had volunteered to step down after struggling to recover from the injury.
Cummings, 35, had been first reserve but created a clamour for his inclusion after a brilliant solo victory on the seventh stage of the Tour de France last week.
British Cycling programme's director Andy Harrison said: "I am disappointed for Pete but I respect his decision and I'm sure he can bounce back and finish his season strongly.
"Clearly Steve is in excellent form and I'm certain he will do Team GB proud."
Chris Froome will lead the team along with Team Sky colleagues Geraint Thomas and Ian Stannard. Adam Yates, currently enjoying an impressive Tour de France where, is also in the team.
Cummings, who rides for the Dimension Data team, had been controversially left out of the initial roster which (apart from Yates) consisted of all Team Sky riders. He said there was a conflict of interest for coach Rod Ellingworth because of his position at Team Sky.
The Olympics road race will be held on 6 August.
