Kazakh rider Yevgeniy Fedorov was handed gold by star teammate Alexey Lutsenko as the pair crossed the line ahead by nearly six minutes in the Asian Games men's road race on Thursday.
The pair, who ride professionally for Astana Qazaqstan alongside British great Mark Cavendish, timed their race to perfection on the challenging 207.7 kilometre (128.7 mile) course through the Chinese mountains.
After sitting in the chasing peloton, defending champion Lutsenko took control with 80km left and the pair stayed together as they pulled clear.
They were seen chatting to each other as they cruised to the finish, with Lutsenko waving his teammate over the line first in 4hr 25min 29sec.
Mongolia's Jambaltsamts Sainbayar came third, 5min 42sec behind.
The dominant Lutsenko, the only rider in Hangzhou to have won Grand Tour stages, had already taken gold in the individual time trial for a third straight time, by a huge two minutes.
Hong Kong's Yang Qianyu stormed to a surprise gold in the women's road race on Wednesday, while Uzbekistan's Olga Zabelinskaya won the time trial.
