Video - GB road race cyclists excel
Britain's cycling success switched from the track to the road as Rachel Morris, David Stone and Sarah Storey added more golds to the team's considerable tally.
Morris, who rides a hand bike, won the women's individual time trial (HCA/B/C) in 20 minutes 57.09secs.
Stone followed up with first place in the Mixed Individual Time Trial (CP1/2) from Germany's Barbara Weise.
And former swimmer Storey won her second Beijing gold with victory in her individual time-trial.
The 30-year-old from Manchester, who was born with a deformed left hand, set a blistering pace as the first rider out on the course at the Ming Tomb Reservoir.
But none of the other nine riders in the final could surpass Storey, married to GB cyclist and fellow gold medallist Barney, who finished over a minute ahead of the USA's Jennifer Schuble with 37 minutes 16.65 seconds.
I did my best and I am completely satisfied with this resul
"I felt really strong although I could feel the pursuit from Wednesday still in my legs a little bit and I was a bit wobbly on a few of the corners," said Storey, who first competed in the Paralympics as a 14-year-old in Barcelona.
"But I'm just ecstatic to have won especially after how close it was on the track."
Surrey-based Morris dominated her race from the very start, winning by nearly three minutes.
"I did my best and I am completely satisfied with this result," said the world hand-cycling world champion. "It is a dream come true."
Darren Kenny and Simon Richardson collected silver medals in their respective races.
Kenny - who won two golds on the track - finished second in the men's individual time trial (CP3), while Richardson finished in 38 minutes 23.73secs, 23 seconds behind the Frenchman Laurent Thirionet.
