Popular Bike Derailleur Brands

The leading brands seen on road and mountain bikes are Shimano and SRAM, while Campagnolo is another prominent brand, specialising in road cycling. Rear derailleurs handle gear shifts at the back of the bike and are compatible with 7 to 12-speed systems, while front derailleurs manage the gear changes at the front, typically offering 2 to 3-speed options.

At Sigma Sports find mountain bike derailleurs designed to take a few knocks from uneven trails or weight saving road bike derailleurs that won't let you down when you are racing.  We've also got these handy guides to adjusting front and rear derailleurs.
