Abstract
A shock absorbing system for a bicycle front fork includes an outer tube and an inner tube which includes a piston located therein, and the lower end of the inner tube is movably inserted into the outer tube. A piston tube is connected between the lower end of the outer tube and the piston. The inner tube includes a first chamber and a second chamber formed therein with the piston located between the first and second chambers. A path formed between the piston and the piston tube. A manual valve is located in the piston tube and includes a rod and a movable part. The rod includes an extension section protruding beyond the outer tube. When the extension section is pushed, the rod moves upward to switch the path from a sealed status to an opened status, and the first chamber communicates with the second chamber.
