Riding for Team Konica Minolta–Bizhub, Chaabane qualified for the Algerian squad, as a 19-year-old, in the men's road race at the 2008 Summer Olympics in Beijing by receiving a berth and finishing fourth from stage four of Giro del Capo in Cape Town, South Africa.
[2] Passing through the 161.2-kilometre (100.2-mile)km mark, Chaabane could not achieve a best possible result with a severe fatigue under Beijing's intense heat and a lapped violation, as he failed to complete a grueling race against a vast field of nearly a hundred cyclists.
On that same year, he and four other international cyclists were stabbed and injured on a house robbery in Potchefstroom, losing some cash, laptops, and five cellphones from their respective belongings.
[4] When MTN Cycling folded after the 2009 season, Chaabane was left with no contract, and ultimately decided to return to Algeria as a freelance agent.
[5] When he joined with Vélo Club Sovac in 2012 under a bi-annual contract, Chaabane added two more titles for an elite level at the Tour de Blida and at the Algerian Road Championships in Mostaganem.
