What are the different types of bike brake levers available in the market and how do they differ in terms of functionality and performance?

There are mainly two types of bike brake levers available in the market: mechanical and hydraulic. Mechanical brake levers use cables to activate the brakes, while hydraulic brake levers use fluid to transmit force. Hydraulic brake levers are known for providing better modulation and stopping power compared to mechanical brake levers. They also require less maintenance and offer more consistent performance in varying conditions.
