Ten years after his accident Teuber competed at his first Paracycling World Championship. In 1998 he took first place in the time trial event at the Road Race World Championship, his first major title. He qualified for the 2000 Summer Paralympics in Sydney, finishing sixth in the Road Race and 7th in the pursuit. Four years later Teuber experienced his most successful Paralympics, securing two gold medals at the 2004 Games in Athens, the Individual pursuit (LC 4) and the &lt;a href="Cycling%20at%20the%202004%20Summer%20Paralympics%20%E2%80%93%20Men%27s%20road%20race/time%20trial"&gt;Time trial/Road race (LC4)&lt;/a&gt;. His gold in the Individual Pursuit was almost lost when the day before the race one of his carbon orthoses, that supported his ankles, broke. With no spares it took two technicians working through the night to construct a replacement in time for him to compete.
