It is cheating when it is against the rules, known about by the participant and ( hidden from an official OR penalized by the official).

Here are two...which if any are cheating?
1 Son does a TT. I think he has junior gears, he thinks he has junior gears. Officials don't do roll out. Two weeks later I am changing cassette and find its one that was used for training and was not legal.
2 Son does Brentwood crit. He wins. He does rollout. He does podium. He says to me it looked like he failed but the referee didn't say/do anything. I look at home - he does not have junior gears.
