<p>A front fork for a bicycle includes an upright tube and two arms (30) all of which are made of fiber reinforced material. The two arms (30) extend substantially parallel from a bottom of the upright tube. The two arms (30) each have two inner tubes (32) abutted together and an outer tube (34) sleeved onto the two inner tubes (32). The abutted portions of the two inner tubes (32) form a rib (33) which is parallel to a plane where the two arms (30) are disposed. Thus, the front fork has strong structure and light weight.</p> |
