forgafler

Forgafler, also written forgaffel in some Scandinavian languages, refers to the front fork of a bicycle. It is the structural assembly that attaches the front wheel to the frame via the head tube and steering axis, allowing the rider to steer while bearing the front load. The fork comprises two legs connected at the crown and supports the steerer tube, which passes through the headset and into the frame.

Key components include the crown, steerer tube, stanchions (upper fork legs), lowers (lower legs), and the dropouts where the axle sits. The fork must align with the frame’s head tube and the wheel’s axle, and it may include brake mounts and mounts for fenders or racks. The crown race at the base of the steerer and the headset bearings enable smooth steering motion.

Forks come in several types and materials. Rigid forks have no suspension and are typically made of steel, aluminum, or carbon fiber. Suspension forks incorporate a spring mechanism (coil, air, or elastomer) and provide travel to absorb impacts. Travel varies by use, with rigid forks offering no travel and suspension forks commonly ranging from roughly 80 to 180+ millimeters, depending on the riding discipline. Carbon fiber, aluminum, and steel are common materials, chosen for stiffness, weight, ride feel, and durability.

Braking and wheel compatibility are important. Some forks support rim brakes, while others are designed for disc brakes and include corresponding brake mounts (post-m or IS). Many forks use different axle standards (quick-release or through-axle) and steerer configurations (threaded or threadless, various diameters). Compatibility with frame, cockpit, wheels, and brakes is essential when selecting a forgafler. Regular inspection for damage and proper maintenance of the headset and bearings are recommended for safety.
