UCI Trials World Championships – Men's trials, 26 inch

The men's trials, 26 inch is a trials event at the annual UCI Urban Cycling World Championships. It has been a UCI World Championship event since 1995.

From 1986 to 1999, the UCI world championships in trials were run as the UCI Trials World Championships. From 2000 to 2016, the world championships in trials were held alongside other mountain-biking disciplines as the UCI Mountain Bike & Trials World Championships. Beginning in 2017, the UCI World Championships in trials are being run as part of the UCI Urban Cycling World Championships.

The '26-inch' designation refers to the wheel diameter of the bikes that may be used in the competition. As this is a standard diameter for a mountain bike, the bikes used in 26-inch trials are also known as 'stock' bikes.
