Video tutorial

To replace the sprocket on the Derbi Senda, loosen all the screws securing the protective panel on the left side. Beneath it, you will find the sprocket and the chain positioned around it. To remove it from its seat, loosen the central nut and completely remove it so that it is freed from the chain.

The new sprocket can then be positioned by placing the chain around it and inserting it into its seat. After securing it, start the bike to ensure everything is functioning correctly.
