Participants in the hardest bicycle races in the world, such as the Race Across America (4800 km), the Race Around Austria (2200 km and 30,000 meters difference in altitude) or Cape Epic in South Africa (700 km, 14,500 m difference in altitude and almost insurmountable terrain), should not only prepare their bodies optimally, but also adjust their sports equipment. Scientists of Karlsruhe Institute of Technology (KIT) have now developed a measurement system by means of which cyclists can adapt their sitting position exactly to their physical conditions.
