However all of this was put into question in February, only weeks after finishing the Tour Down Under. There were abnormalities in his biological passport and so this led to a
suspension. Reportedly, the firing of team boss Vincent Lavenu also came as a consequence of the case, as the manager did not inform other entities in proper time leading to insatisfaction.
Bonnamour has spent the large part of this year trying to prove his case but is now forced to give up as it is too much of a financial effort: "It is too costly in financial terms, I am stopping. I can't afford to lose everything and I'm financially blocked," he has told Ouest-France. "It's been difficult for six months, I didn't want it to last two years, three years like this. My priority is to maintain a family balance. Morally, there are difficult times, I am supported by my family and I am also being followed psychologically. I am afraid of the future. I know what I did, what I didn't do".
