ABSTRACT:
The forks of a bicycle are carried by a head tube shaft and are angled forward and comprise two outer support tubes, one on either side of the wheel. An inner suspension tube is telescopically housed in the outer tube and connects to the wheel axle. A suspension spring within the outer tube urges down. A torque reaction arm is journalled on the axle and carries a brake calliper within which passes a brake disc. At the rear end of the arm, a rear link is pivotally connected and leads up to an upper pivot point on the outer tube. Application of braking torque causes the rear link to act upwards on the outer tube, providing anti-dive.
