ABSTRACT:
A motorcycle or bicycle having a fork with swappable trail adjustment blocks which hold the front axle to the fork. Trail can be adjusted without removing the forks or even loosening them in the triple clamps, and without altering ride height or rake angle. Brake caliper mounts are swapped when the trail adjustment blocks are swapped, moving the brake calipers the same distance and direction as the axle, to maintain a constant radial distance from the axle to the brake pads. The brake caliper mounts pivot on the forks, enabling the brake calipers to be swung outward so the wheel can be changed without removing the brake calipers from the forks.
