Abstract

An invented angle-adjustable front speed-changer of bicycles (3) includes a speed-changer body, a circular fixed seat provided to fix the speed-changer body. Where the circular fixed seat comprises an arc fixed part and an arc moving part hinged on the arc fixed part. The fixed part and the moving part are connected by a bolt. Besides, inside of the fixed seat sets a lining, where the axial section of the lining shows as an arc salient. In case of adjusting the angle of the speed-changer, the procedure can be achieved by just modulating the deflection angle of the fixed seat. Therefore, the invention can be employed in different variety of bicycle's tubes by means of only adjusting angle and then fixing it.
