A trials rider competing in the 26-inch category of the 2010 UCI Trials World Championships in Mont-Sainte-Anne, Quebec
The UCI Trials World Championships are the world championship events in trials organised by the Union Cycliste Internationale (UCI), the governing body of world cycling.[1] The first three finishers in each category are awarded gold, silver, and bronze medals. The winner of each category is also entitled to wear the rainbow jersey in events in that category until the following year's World Championships.[2]
Separate titles are awarded for men and women. The men's events include categories for junior and "elite" (an open age category) using bicycles with 20" and 26" wheels. There is also a team event, in which each country enters one junior and one elite 20" rider, one junior and one elite 26" rider, and one female rider.[4]
From 1986 to 1994 there were no separate categories for bikes with different wheel sizes. The 20" and 26" categories were introduced in 1995. The women's category was introduced in 2001. A team event has been included since the first UCI world championships in 1986, though the format has varied over time.[5]
