A bicycle gear shifter is a device that allows cyclists to change the gear ratio of their bicycle, which in turn changes the amount of force required to pedal and the speed at which the bicycle travels. Gear shifters are typically mounted on the handlebars and are operated by hand or thumb.
Gear shifters are an important part of any bicycle, as they allow cyclists to adjust the gear ratio to suit the terrain they are riding on. For example, a cyclist climbing a hill will need to shift into a lower gear to make pedaling easier, while a cyclist riding on flat ground will be able to shift into a higher gear to travel faster.
There are two main types of gear shifters: indexed and friction. Indexed shifters are the most common type and use a ratchet mechanism to move the chain between gears. Friction shifters, on the other hand, use a friction mechanism to hold the chain in place. Friction shifters are less precise than indexed shifters, but they are also more durable and can be used on a wider range of bicycles.
