<p>A front fork (10, 30) for a bicycle includes an upright tube (20, 32), a fork crown (22, 34) and two branch tubes (24, 36). The fork crown (22, 34) is mounted on a bottom end of the upright tube (20, 32). The branch tubes (24, 36) each have a top connected to the fork crown (22, 34), and a rib (26, 38) located inside an upper section (28, 40) thereof. Thus, the upper sections (28, 40) of the branch tubes (24, 36) have well structural rigidity for increasing the transmission efficiency of the bicycle. The lower sections (29) of the branch tubes (24, 36) have well flexibility for enhancing the rider's riding comfort.</p> |
