The Canadian Olympic Biathlon team are putting new roller skis to the acid test - 1,000 kilometers through the Rocky Mountains. Arno Barthelmes has come along. The entrepeneur from eastern Germany developed and built the sports equipment. Now he's hoping to sell them to the Canadians. He already counts the Swedish, Austrian and German Biathlon national teams among his clients. The former car parts supplier is using roller skis to pull himself out of the crisis.
