SASCOC says Jeanne Nel, a former national sprint, time trial and Keirin champion, died after the crash at a velodrome in Bellville near Cape Town on Tuesday.
Cycling coach Ricky Kulsen says Nel was ''one of the best sprinters South Africa has ever had ... a true champion lost to South African cycling.''
The Olympic committee said on Wednesday that Nel was a member of the South African men's sprint team attempting to qualify for the Commonwealth Games in Glasgow, Scotland in July and August. It didn't give any detail on the cause of death.
Cycling South Africa said ''we're shocked at the devastating news.''
