Fit And Set Up A Front Derailleur

Introduction

Setting up a new front derailleur can be frustrating, as it doesn't have much adjustment. For this reason, it's important to get it in the right place when you fit it in the first place. Modern bikes come with many different combinations of derailleurs and gears, so make sure your set up is compatible.

This is a long guide, so you can choose to either watch the entire video above, or follow it in smaller chunks by clicking on the individual steps below.

Front derailleur adjustment and set up should be performed after the rear derailleur is working. Then go back and check the operation of the rear derailleur with the chain in all positions at the front.

3. Diagnose Chain Length For Derailleurs

On a derailleur gear system the chain shifts between cog wheels of different sizes. The system adapts to the demands for different amounts of chain with a spring-loaded arm that moves the bottom jockey wheel backwards to increase or decrease the path the chain must follow.

4. Connect A Chain With A Chain Tool

Any single-speed or standard derailer chain can be connected with chain tool. Narrow 9, 10 or '11 speed' chains have plates that are too thin to make this a reliable process and connect with special links that are supplied with them. Some chains – for example Shimano - have to be broken and reconnected with a special pin. Others with a trick link that can be dismantled by hand.
