These handy devices enable you to shift gear, as well as help to keep your chain on. Otherwise known as front derailleurs, they are designed to work with a specific number of chain rings (either double or triple) and speeds (from 7/8 speed all the way up to 11). You need to establish that your new front mech will both fit your frame, as well as be suitable for your current drivetrain. If in doubt, try to replace the older model with a similar derailleur - you won't need to replace front mechs as often as rear, in some cases they can last decades! The industry leaders in this department are Shimano, SRAM, and Campagnolo, although companies such as FSA also produce their range of derailleurs too.
