Dual-crown forks clamp the steerer tube at both the top and bottom of the head tube, dramatically increasing torsional and fore-aft stiffness. This is critical for DH because the extreme loads of high-speed rough terrain can cause single-crown forks to flex, reducing steering precision. Dual-crown forks also allow 200mm of travel while maintaining chassis stiffness. The trade-off is weight, cost, and a taller front end.
