How to Use Downtube Shifters

To change gears, you have to move the lever, and the derailleur moves until the chain jump from one chain to the other. If you move too far, you will hear a noise; adjust the lever gently until the noise goes away. You will use the right hand to shift the rear derailleur and the left hand to shift the front.

These shifters have two elements – the lever and the barrel. The lever is the apparent aluminum handle that sticks out, and the barrel is the round bit attached to the bike frame. The cable itself is connected to the lever and then the derailleur. 

If your derailleur is out of adjustment, it will be harder to function correctly. 

Some modern entry-level road bikes with downtube shifters come with indexed shifters. Others have a little control attached to them to switch from indexed to continuous mode.
