Basic Features of Bicycle Front Fork

The bicycle front fork is a key component that connects the handlebars to the front wheel, serving both guiding and shock-absorbing functions.

Core Functions
Guiding Function: Controls the direction of the front wheel through turning the handlebars.
Shock-Absorbing Function: Absorbs road impacts, enhancing riding comfort and handling stability.

Main Categories (by suspension medium)

Spring Fork
Uses metal or titanium alloy springs as the elastic medium.
Simple structure, low cost, durable, but relatively heavy.
Mostly used in entry-level or commuter models.

Air Fork (Oil-Air / Dual-Air)
Uses compressed air as the elastic medium, combined with an oil damping system.
Lightweight, highly adjustable (hardness can be adjusted by inflating), but requires regular air pressure maintenance.
High-end models (such as SID, Reba) are widely used in XC cross-country biking.

Oil-Spring Fork
Combination of spring + oil damping, with good linear rebound and sensitivity to small vibrations.
Heavier, but rigid and suitable for intense mountain biking.

Resistance Rubber / Urethane Fork
Uses foam materials as the medium, lightweight and maintenance-free.
Prone to aging (needs replacement approximately every 2–3 years), gradually phasing out from the mainstream market.
