Cyclist Megan Fisher of Hinsdale won the gold medal Wednesday in the C4 time trial at the 2012 Paralympics.
Fisher, a below-the-left-knee amputee as a result of a car crash a decade ago, clocked 26 minutes, 4.39 seconds to beat Sarah Powell of Australia by nearly 27 seconds.
"It was a really strong field," Fisher said. "I've been going back and forth with Susan Powell for a couple of years now."
Fisher, 29, a doctoral student at the University of Montana, won a track cycling silver medal in individual pursuit last week.
Oswego's Joe Berenyi added a third Paralympic medal Wednesday, a silver in the C3 time trial. His time of 23:31.73 was 9.6 seconds behind winner David Nicholas of Australia. He had won gold and bronze in track events.
"It completes it (a full set of medals)," he said.
Paralympic classifications reflect disability level relative to the sport, with a lower number indicating a greater disability. Berenyi, 43, lost his right arm in a construction accident 18 years ago.
Road cycling presents greater control issues for disabled athletes than velodrome races, especially with windy conditions like those Wednesday on a course at the Brands Hatch Formula 1 track.
"You've got to pay attention to the road conditions, bumps in the road," he said. "In the velodrome, the bike pretty much goes by itself.
"(Today) was a bit tougher than I thought with the wind. I had to slow down on some of the turns. Handling with one arm in those speeds, I was blowing around a lot."
In the C5 time trial, Greta Neimanas of Chicago, born without a lower left arm, placed fourth in 25:25.51, 11 seconds behind bronze medalist Kelly Crowley of San Francisco. Paralympic cycling superstar Sarah Storey of Great Britain won her third gold medal of the Games in 22:40.66.
