Definitions

Types of courses that are primarily downhill and very technical with large obstacles and jumps. Best for bikes with larger tires (2.5") for traction, heavy duty frames, long travel (e.g., 8 inches).

Similar to downhill, but with less technical terrain, often including manmade portions, stunts and jumps.

A combination of both downhill and cross country terrain. Bikes are made to pedal very well and descend easily, so you get the best of both worlds. Best for bikes with large tires (2.3"), heavier duty frames, and longer travel (e.g., 5-6 inches).

Trails and off-road paths that require bikes that are more durable and easy to control. Best for bikes that are small, heavy duty, and easily controllable.

Road courses that are primarily flat. Although many bikes can be used on these courses, bikes specifically designed for these have seat tube angles that are greater than standard road bike seat angles to allow a person to get in a more aerodynamic position over the handlebars.

All types of road courses, including mountain ascents and descents, and cross-country riding. Many bikes can be used on these course, but bikes specifically designed for maximum efficiency have narrow tires for low rolling resistance, light frames for increased power to weight ratios, highly refined shifting systems for smooth gear transitions, and frame designs to maximize efficiency but minimize road chatter.

All types of road courses, bike paths, and light off-road trails. Bikes designed for this category employ benefits of both road and mountain bikes. They have lighter frames and narrow tires for increased efficiency, but have mountain bike bars and shifters that allow you to sit up straighter in a more relaxed position.
