Question

Where were the first world championships for mountain bike racing, sanctioned by the Union Cycliste Internationale (UCI) in 1990, held?

Answer 1

The first UCI Mountain Bike World Cup series took place in 1988. Its nine-race circuit covered two continents—Europe and North America—and was sponsored by Grundig. Cross-country racing was the only World Cup sport at this time. In 1993, a six-event downhill World Cup was introduced.
