Abstract
A wheel suspension system for a bicycle is provided with a telescopically coupled sliding tube and a fork leg forming a suspension assembly with a shock absorber assembly. The fork leg is provided satisfactorily high rigidity for withstanding torsional torque which is potentially exerted through a brake lever during application of a brake. The fork leg with sufficient rigidity can be formed from a tubular material. For this purpose, the wheel suspension system comprises a pair of left and right sliding tubes secured to a steering bracket which is rotatably supported in the front portion of a body frame of the bicycle, a pair of left and right fork legs supporting a front wheel and slidably receiving corresponding one of the sliding tubes, shock absorber assemblies respectively disposed between respective sliding tubes and the fork legs, cross member holders externally mounted on the outer peripheries of the upper portions of the fork legs, and a cross member provided with a predetermined torsional strength and bridging over the cross member holders.
