Huffy Derailleur Installation

The derailleur on your Huffy bicycle sits next to the back wheel. The drive chain of the bike runs through the derailleur, which is operated by the shifter on the handlebars. When you move the shifter, it pulls a cable that moves the derailleur, thereby moving the chain from cog to cog to switch gears. When the derailleur or any of its small parts break, install a new derailleur on your Huffy bike to save some money on maintenance costs.
