| The gearing system on your bike is, next to your brakes probably the next most important part of the bike (assuming you also include the chain). |
|
In this section we provide a quick summary of the different components within the gearing system and the different types of them.
Rear derailleur
Mountain Bike Rear Derailleur
This has a long chain cage and is usually controlled by a handlebar gear shifter.
Road Racing Rear Derailleur
This has a short chain cage. This keeps the weight of the bike down and makes gear changing easier. The shifter on the down tube of the frame or STI/Ergo power levers, on the handlebars controls it.
Economy Rear Derailleur
This one is made of steel. It bolts straight into the frame rather than onto a gear change hanger.
Front derailleur
Mountain bike front derailleur
This has a wide chain cage to accommodate triple chain rings that have big jumps in size between them. An indexed shifter on the handlebars controls them.
Road racing front derailleur
This is a light chain cage is less wide to accommodate the 2 chain rings normally present on this type of bike.
Hub gears
Five or Seven-Speed Hub Gears
They are designed as low-maintenance gears for city bikes. Again a click shifter of some description fitted on the handlebars controls these.
Three-speed hub gears
These are for utility bikes and have a click shifter on the handlebars.
