Downhill mountain bikes

Downhill cycling is a time trial event where riders race down steep (and often treacherous) courses. As the name implies, there is no climbing involved; the momentum is gravity-based and riders travel at very high speeds. Because of these demanding conditions, downhill mountain bikes require disc brakes and full suspension.

Downhill mountain bikes have a geometry that leans back further and more suspension travel than other bicycles (usually 8”-10” of travel). Both of these features prevent riders from going over their handlebars during steep sections of the course.

Disc brakes stop movement at the center of the wheel instead of the rim. Due to the muddy nature of some courses, standard brakes (rim) can become wet, ineffectual, and dangerous. Pneumatic disc brakes stop heavy bikes even at high speeds and that’s why they’ve become standard on downhill mountain bikes.
