There are two main types of front derailleurs: top- and bottom-pull. Both work similarly by moving the chain across various cogs on the cassette, but they’re best-suited for specific drivetrains. Most mountain bikes still come with a standard front derailleur, and if you’re going to stick to one gear ratio, they’re a good option. Shimano’s mountain bike derailleurs are a popular option and feature a single-ring configuration.
Road bikes and bikes with more gears tend to have a front derailleur. There are many front derailleurs to choose from, but the Shimano Sora is one of the most popular options for the money, especially for the variety of bike it’s compatible with. It can handle a compact or standard configuration, and many riders love how durable it is.
To help you find the best front bike derailleur for you, we’ve rounded up the top options on the market.

Best Front Bike Derailleurs Buying Guide
Before choosing the best front derailleur you should consider following options:
1. Cable Management: Good cable management is essential to prevent a derailleur from jamming. It’s best to have the cable exit the derailleur cage at the top and bottom, so that the cable can be run in a straight line without unnecessary bends.
2. Cage Size: It’s important to get the right cage size for your frame. If the cage is too long, the chain may hit the frame or the frame dropouts. If the cage is too short, you may end up with too much chain on the smaller cogs.
3. Maximum Chainring and Cassette Cogs: You want to make sure there is adequate room for the largest chainring and smallest cog on your cassette. For example, if you have a 53/39 chainring and 11-25 cassette, there should be enough room for the small cog and the largest chainring.
4. Fit: You want the derailleur to fit properly on the bike. The derailleur should be aligned with the chainrings and the cable should be tensioned properly.
5. Looks: With the multitude of options available today, you can be sure to find something that suits your tastes.
