Video - Second gold for Kenny and Stone
Britain's Darren Kenny continued his incredible gold medal-winning haul when he won the men's individual road race.
The 38-year-old pipped Spain's Javier Ochoa by just 1.74 seconds over the 60.5km course to claim his fourth top podium finish in Beijing.
"It came down to Javier and me and we sorted it out between us over the last 150m or so," said Kenny.
Earlier team-mate David Stone captured his second gold in the mixed individual road race, GB's 17th cycling success.
The Leeds-based rider, who won gold in the individual time trial, finished almost three-and-a-half minutes ahead of South Africa's Riaan Nel.
Stone, who has cerebral palsy and rides a tricycle, crossed the finishing line in a time of 45 minutes 05.33 seconds, to clinch Britain's fourth road cycling gold.
"This is what I've been working towards for a long time. I feel fantastic, amazing," said Stone.
I think my calves would have popped if the race had gone on another 10 metres
Kenny, who has cerebral palsy, capped off his fifth and final race of a memorable Paralympics with yet another victory, although the Dorset cyclist was not expecting his success.
"I didn't think I was going to get anything today," said Kenny, who won three golds in the velodrome. "I didn't feel too good and was really struggling for the first couple of laps."
"By the end everything was on the verge of collapsing. I think my calves would have popped if the race had gone on another 10 metres."
Team-mate Rachel Morris finished in sixth place in the individual hand cycling road race (HC A-C).
Morris, who won gold in the women's individual time trial on Friday, could not maintain the fast pace set by winner Andrea Eskau of Germany.
Men's 1km time trial champion Mark Bristow finished 24th in the LC1-2/CP4 road race, while Simon Richardson finished 10th in the LC3-4/CP3 category.
