What is a threaded fork?
A threaded fork is a type of front fork that is commonly found on older or more traditional bicycles. It is called “threaded” because the steerer tube has screw threads on the top, allowing for adjustable height and secure attachment of the fork to the frame.
A threaded fork consists of three main parts: the steerer tube, the crown, and the blades. The steerer tube is the long tube that extends from the crown and is inserted into the head tube of the bike frame. The crown is the part that connects the blades to the steerer tube, and the blades are the two long metal tubes that hold the front wheel.
Threaded forks are typically found on bikes with external headset systems, meaning that the headset bearings are housed outside of the head tube. This design allows for easy adjustment and maintenance of the fork height and bearing tension by simply loosening or tightening the top locknut.
Installing a threaded fork involves removing the old fork, attaching the new fork to the frame, and then adjusting the height and bearing tension to ensure proper alignment and stability. It is important to use the correct tools and follow the manufacturer’s instructions to ensure a safe and secure installation.
Threaded forks are becoming less common on modern bicycles, as they have been largely replaced by threadless forks. Threadless forks offer advantages such as increased stiffness, lighter weight, and easier adjustability. However, threaded forks are still found on many older bikes and can be a reliable and durable option for riders seeking a classic or vintage-style bicycle.
