What are the different types of bike gear derailleur available in the market and how do they differ in terms of performance and functionality?
There are three main types of bike gear derailleurs available in the market: front derailleurs, rear derailleurs, and electronic derailleurs. Front derailleurs shift the chain between the front chainrings, while rear derailleurs shift the chain between the rear cassette gears. Electronic derailleurs use electronic signals to shift gears instead of mechanical cables.
In terms of performance and functionality, front and rear derailleurs are typically more affordable and easier to maintain, but may require more manual adjustment. Electronic derailleurs offer faster and more precise shifting, as well as the ability to customize shifting patterns. However, they are usually more expensive and may require specialized tools for installation and maintenance. Ultimately, the choice of derailleur type depends on individual preferences and budget.
