Abstract

A base of a shock-absorbing front fork for a bicycle includes two straight tubes and a bridge. The bridge has two ends connected integrally with an upper section of each of the straight tubes. The bridge has a chamber therein. Thus, the base of the shock-absorbing front fork has the advantages of high structural strength and long service life.
