Riding for , 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. Passing through the 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. Chaabane signed an annual contract with pro cycling team in 2009. 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. When folded after the 2009 season, Chaabane was left with no contract, and ultimately decided to return to Algeria as a freelance agent. In 2010, Chaabane earned his first career title in road cycling for the under-23 division at the African Championships in
Tunis,
Tunisia. 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. In April 2015, it was announced that Chaabane had tested positive for two undisclosed prohibited substances and was provisionally suspended from racing. ==Major results==
