Road front derailleurs
For 2x and 3x road drivetrains, you’ll need a front derailleur or ‘mech’. There are quite a few things to think about when buying a front derailleur. Firstly check whether you need 2 or 3-speed and how many gears you have; for example, if you have a 9-speed setup, then you’ll need a 9-speed front derailleur to match. Secondly, check if you need a ‘direct mount’ derailleur that bolts to the bike frame or a ‘band clamp’ type with an integrated clamp that mounts around the seat tube. A band clamp will have to fit around the frame, so you’ll need to check the diameter your frame. You should match the front derailleur to your existing groupset – Shimano, SRAM and Campagnolo may not work together well. Although you can mix components, it’s generally easier to stick to one brand to ensure smooth shifting. If you have electronic shifting, then it’s essential to match components as different brands will simply not work together.
