The humble bicycle derailleur can trace it’s roots all the way back to 1905 and despite the emergence of cutting edge gearboxes from smaller volume manufacturers, the time-proven derailleur is still the most efficient form of drivetrain for a pedal powered bike. Front and rear derailleurs look after the slick changing of gears through a cassette or across chainrings and come in a variety of speeds and mountings to suit various bikes and budgets. We stock a huge range of derailleurs to suit road and mountain bikes from entry level 7-speed derailleurs right up to the latest electronic derailleurs for high spec road bikes.

If you’re a mountain biker looking to upgrade your drivetrain then derailleurs are a great place to start. Constantly losing your chain on rough ground or sick of the sound of the chain slapping against your frame and ruining your paint? Then you might want to check our range of clutch equipped derailleurs designed to keep your chain where it’s supposed to be. Perhaps you want the latest wide range cassette and need a new derailleur to match? Once again, this is the place you need to look!

Road bike derailleurs are much the same as their mountain bike cousins, with the same basic design and operation. Upgrading your bike's derailleurs is a great way to improve shifting performance, which makes your bike feel smoother, faster and more reliable. We stock a huge range of front and rear road bike derailleurs to suit almost any road bike, so if you need to upgrade or replace a derailleur on your bike, you’ve come to the right place! Check out the full range of new derailleurs, parts and accessories from Shimano, SRAM, Campagnolo, Tacx and Hope Technology.
