When you're buying a road bike, the range of bike types, materials and component options can be bewildering. Let us steer you through your choices and help you find the right road bike for you.

There's never been a better time to buy a new road bike. While the likes of Wiggo and Froome might belt around France on bikes costing anything up to £10,000, you don't need to spend anywhere near that much. Over the last couple of decades entry-level bikes have become ever better value for money, with much of that Tour de France advanced technology trickling down to bikes we can all afford.

First, you need to decide how much you're prepared to spend. Decent road bikes start from about £250; the more you spend the lighter and better specified a bike will be. There is no right price. There's a great choice between £300 and £500, and from £600 to £1000 you're entering the territory of very capable road bikes. Beyond that, well, you're entering a world of choice to suit all tastes.

Do your research

With a budget in mind, you want to do some research. Sure, you can just walk into your nearest bike shop, slap down some cash on the counter and leave with a road bike, and there's nothing wrong with that. But a bicycle is an investment and, as with most expensive investments, it's worth spending some time researching the options.

Our forum is a great place to ask questions about road bikes, and our review database gives you valuable advice for sorting the wheat from the chaff. They're both very good places to start. Below we outline some of the important considerations to think about.

Frame materials

The frame is the heart of your new road bike and it's where the majority of the budget goes. Frames are made from a range of materials, the most common being steel, aluminium, titanium and carbon fibre. Broadly, frames made from any particular material will have common characteristics, though what the designer does with a material is as important as the material itself.

Aluminium is the most common frame material for road bikes costing under £1,000. It's inexpensive, and a very good material to make bikes from because it builds into stiff, light frames. The latest aluminium frames boast some advanced features and design touches.

Better aluminium frames use butted tubes (where the wall thickness is varied along its length) which makes them lighter and can offer more comfort. Frames with stickers indicating the use of tubing from top manufacturers Dedacciai, Easton, or Columbus will command a premium.

Steel was the dominant road bike frame material until the 1980s and is still a lovely material in the hans of a good designer. It's most often found on custom bikes and those designed for touring because in those applications its weight penalty is less important. It's heavier than aluminium but can be wonderfully comfortable. The latest ultra-high-strength stainless steel tubes from Columbus and Reynolds demonstrate the material's suitability for lightweight race bikes but they don't come cheap.

Titanium was once the most exotic material of them all. A titanium frame can be as light as aluminium and as durable as steel, making it a wonderful material for bicycles and its corrosion-resistance is the icing on the cake. It is, however, difficult to work with and this means that it has always been an expensive option, although it is steadily becoming slightly more affordable.

Carbon fibre is now the most coveted road bike frame material. Once an ultra-expensive choice, bikes with carbon fibre frames are now available from about £900.

Carbon fibre frames aren't all equal though. There's a huge difference between cheap and expensive carbon fibre, down to the type of fibres used, how it's manufactured and other important factors that make a big impact. Carbon fibre can be relatively easily manipulated by designers to create frames with the particular balance of properties they want, whether that's low weight, comfort, stiffness.

If you're facing a choice between a bike with a carbon fibre frame, and another with an aluminium frame, don't dismiss aluminium. Often you will get an aluminium bike with higher grade wheels and components than you could get on a carbon bike of a similar price, and that will contribute to a lower overall weight. That can lead to a far more enjoyable ride than you'll get from a carbon fibre bike where the manufacturer has had to cut corners (with heavy wheels or a low spec groupset) to make a price point. So don't just put carbon fibre at the top of your list because your friend has bought a carbon fibre bike.

Choosing the right size

Choosing the right size bike is absolutely critical when buying your first road bike. Take advice from the bike shop but don't go for a bike that is too small or too large just because it's a bargain. Only with the correct size bike for your height and dimensions will you really get the most out of your new hobby.

Picking the right size can be difficult. Generally, road bike sizes are given in centimetres but the way in which frames are measured varies between manufacturers. Some offer three sizes and some offer 10 with smaller increments between them. However, as everyone has their own individual body shape it can get complicated.

The best thing is to have a good look at the size chart on each manufacturer's website, and sling your leg over any bike you're considering buying. If you can get a short spin on a bike, even better. The minimum rule of thumb is that you should be able to stand over the frame with a couple of centimetres of space between you and the top tube. If you can't, it's definitely too big.

If the bike fits

Bike fit services have become popular these days, and many bike shops offer such a service. They'll give you expert advice and will even fit you on the bike in the shop to make sure you leave a happy customer.

There are several parts of the bike that you can change to help find a good fit, and a good bike shop will be invaluable here. The height and fore-after position of the saddle can be adjusted. The handlebars can be raised or lowered with spacers on the steerer tube. Stems come in a range of lengths with 10mm increments to help you get the right reach. These are all changes that a good bike shop will happily assist you with.

Components

Bike component manufacturers assemble their parts into groupsets — collections of brake and gear parts matched for quality and function and designed to work together. Bike makers buy groupsets to build into bikes. There are three major manufacturers that you're likely to encounter: Shimano, SRAM and Campagnolo. At entry-level prices, Shimano is the most popular choice.

The order of quality and price for Shimano goes like this, from entry-level to top-end: Claris, Sora, Tiagra, 105, Ultegra and Dura-Ace. Campagnolo starts with Veloce, then Athena, Chorus, Record and, at the very top, Super Record. SRAM offers four road groupsets: Apex at the entry level, Rival, Force and Red. Pay more and you get better performance, lower weight, or both.

Each manufacturer has different controls for its gear shifting, though they are all built into the brake levers, and it's down to personal preference which you choose. Shimano and Campagnolo also offer electronic shifting versions of their top groupsets although they command high prices.

Compact, standard or triple chainrings

The chainset (the part the pedals attach to) comes with chainrings of various sizes. On an entry-level bike you'll usually find a 'compact' double chainset, with 50 and 34-tooth chainrings to give low ratios that make getting up hills easier.

Racing cyclists usually prefer a standard double chainset. A larger pair of chainrings (usually 39/53) is better suited to the high speeds of racing in a bunch.

It's still possible to get triple chainsets on road bike, although they have mostly been replaced by compacts, which offer nearly the same spread of gears but they're lighter and simpler to use. Triples are good for those who want the very lowest gears, and they're ideal for really steep hills or riding in the mountains.

The wheels make the bike

The next important area of your new bicycle is the wheels. The wheels heavily influence how the bike rides, feels and responds. Lighter wheels will ride faster with less rotating mass. Lighter and faster tyres feel more responsive.

When researching your new bike, decent wheels should be high on your list of priorities. While you can easily replace components like the rear derailleur and other components that will eventually wear out, the wheels take up a large chunk of the bike's overall cost so they're more expensive to upgrade.

So there you go, some useful tips and hints for making the right choice when it comes to buying your first road bike.

One thing you don't mention is mudguards. You need to decide early on if you are going to want or need mudguards mounted on your bike on a regular basis. If you are choose a frame with eyes and long drop brakes

If your selected frame doesn't have the clearances or eyes for full mudguards then most/all of the solutions are unsatisfactory in one way or another and if you are going to leave them permanently mounted for winter commuting then you will at sometime end up kicking them at the side of the road.
