Abstract

The present invention concerns a speed gear comprising a geared rod moved by the chain aimed at making the back wheel rotate. Said rod is formed by a series of geared sectors (5) radially sliding in the same way, thus modifying the total diameter of said rod, which allows for transmission variation.Said process can be easily carried out by means of a little handle (1) set on the bicycle framework, as it is envisaged in traditional speed gears.(Fig.1).
