What are the two types of shifters used in cycling?

The two types of shifters commonly used in cycling are thumb levers and twisting handlebar grips. Thumb levers are typically used on mountain bikes and allow the rider to shift gears by pushing a lever with their thumb, which can be a quick and efficient method of changing gears without taking the hands off the handlebars. On the other hand, twisting handlebar grips, also known as grip shifters, involve twisting the grip of the handlebars to change gears, which can provide a very intuitive and seamless way to shift while maintaining grip on the bars.

This distinction between the two types of shifters is important for cyclists to understand, as it can influence their choice of bike and the style of riding they prefer. Each type offers a different experience in terms of ease of use, speed of shifting, and comfort, and cyclists may choose one over the other based on personal preference or terrain.
