Cooper, 19, beat team-mate Samuel Gaze, 18, into second in a sprint finish with Australian Daniel McConnell in third.
Scotland's Grant Ferguson, 20, finished fifth with England's 2006 winner Liam Killeen in sixth.

In the men's race, only 10 seconds separated the first three riders, who dropped Max Plaxton of Canada on the seventh and final lap.
Cooper completed the 37km course over the Cathkin Braes Trail in one hour 38 minutes 26 seconds.
Pendrel had earlier dominated the women's race to take gold in a time of one hour 39 minutes 29 seconds.

Canada have now won gold on each of the three occasions the event has been included in the Commonwealth Games programme.
Australian Rebecca Henderson took the bronze with England's Annie Last pipping team-mate Alice Barnes for fourth place.
