A derailleur (or mech) is what changes the gear on your bike so it's an important piece of kit. You'll need to make sure to match the brand of mech you get to the brand of gear shifters you have, and also to match up the number of sprockets with your cassette or freewheel (although on the whole a mech with more sprockets will work with a freewheel/cassette with less sprockets).
Tyres are a pretty vital part of your bike, so choosing the right one is crucial. Road tyres come in two different types: we have clincher tyres for those who want to ride along the roads, whilst road racers should get tubular tyres which don't need an inner tube.
The off-roaders are going to want some knobbly ATB tyres: they come in different treads depending on your needs.
Finally there are hybrid tyres for commuters or those who just want to leisurely cruise along.
The "caked in mud" look is not one of the most stylish, so if you want to keep yourself and your bike's frame (relatively) clean then we recommend a mudguard to keep that spray at bay. Easy to fit to either your bike's front or back wheels, now you'll be able to arrive at work looking much more respectable.
V Brakes are the more modern choice of rim brake and you certainly get bang for your buck with these. Reasonably priced yet packing a punch, these brakes work well on Mountain Bikes with suspension as well as Hybrid Bikes. Alas, V Brakes will eventually wear down and when that time comes, we've got a whole host of options for you.
Unless you have a tubular tyre, you're going to want an inner tube. Without one, you won't be going any place fast. Inner tubes will sometimes tell you in their name what type of cycling they're designed for, so make sure you don't buy a road inner tube if you're going to be downhill racing!
It's also pretty important you buy an inner tube in the correct size for your tyre, and that it has the correct valve. That's a lot to get right, but we've got enough choice to keep you rolling along!
Pedals are your connection to your bike. Without pedals, you're not going far! They come in a variety of different types so make sure you know what you need: we have your ordinary flat pedals, clip-in pedals, pedals for different types of bikes and snazzy SPD pedals.
Stunt pegs attach to your bike's wheels and allow you to jump onto them to hop around on and do awesome tricks.
Along with fire, it's fair to say that the wheel is one of the human race's most important inventions and it's come a long way from the days of yore. We have a huge selection of the most cutting-edge designs around today for all types of bike: rugged wheels for MTB, sleek and speedy wheels for Road Bikes, solid wheels for stunts on BMX Bikes and your general all-rounders for leisure riders. Our wheels will keep you rolling along for years.
Who knew there were so many different types of handlebars? As with all things bike, it comes down to a split between rider's preference and type of bike. Mountain Bikes and Hybrids have flat handlebars and they're usually the type of handlebar we all start off with. Road Bikes have drop handlebars which allow for you to make yourself as streamlined as possible. Both drop and flat handlebars are available in different types so if you're not sure what you need, we're happy to help.
You won't be able to steer your bike without a headset. A headset is a set of bearings that enable the handlebars to be turned, and there are two types: traditional threaded headsets and the more modern A-Headset. As well as knowing what type of headset you need, you'll need to make sure you get the correct size for your fork steerer tube so you can steer your bike until your heart's content.
Getting off a bike unable to walk isn't very fun, and quite often a different saddle can do wonders for your comfort levels. Alas, what works for one person won't always work for another: we're all built a bit differently, and the design also differs according to what type of cycling you do. But never fear! We sell a wide selection of saddles for any and all needs.
Seatposts are what connect your saddle to your bike's frame - you're going to want one of these unless you fancy a saddle-less ride.
Bike forks differ depending on what type of bike you have and what you use your bike for. We have rigid bike forks for road, hybrid and BMX bikes but if you like to take your bike off-road, then a suspension fork is what you're after. A suspension fork will help you glide over the toughest terrain without bashing you around too much. For tougher terrain you'll want a suspension fork with more travel; for cross-country you don't need as much.
