Derailleurs on old bikes perform the same function as on modern bikes, but they may have specific features and standards depending on the era and type of bike. Here is a general description of their function, characteristics and standards:

Function :

The derailleur on an older bicycle allows you to change gears by moving the chain from one cog to the next on the cassette or gear block at the rear of the bicycle. This allows the cyclist to adapt the pedaling resistance according to the terrain and the speed of travel.

Features :

1. Materials:

Derailleurs on older bicycles were often made of steel or aluminum alloy, with components that were sometimes more massive and less sophisticated than those used on modern bicycles.

2. Design:

Derailleurs on older bikes may have a simpler, more classic design, with clean lines and basic functionality.

3. Compatibility:

They are designed to be compatible with the specific transmission systems of their era, which may differ from current standards in terms of number of gears, cassette type, etc.

4. Maintenance:

Some older derailleurs may require more regular maintenance and gentler handling due to their older design and materials.


Derailleurs on older bicycles may be specific to a particular manufacturer or model of bicycle, but they are generally designed to be compatible with bicycle industry standards of the time. However, there may be variations depending on the period and country of origin of the bike.

In summary, derailleurs on old bicycles perform the same basic function as on modern bicycles, but they may have specific features and standards depending on the era and type of bicycle. They are designed to be durable and reliable, although they may require special care and handling due to their age and design.
