When choosing a road bike, start with the correct size, a position you can maintain and the routes you will ride: for beginners, endurance geometry is often a good starting point. An aero model makes sense if you want speed and can comfortably maintain its riding position; brakes and gearing should then be chosen according to your riding and overall budget.
How to choose
Before considering the brand or specification, ask yourself how long your rides will be, how much climbing you will encounter and whether you want to ride for pleasure, in a group or in races.
- Leisurely rides and long distances: prioritise position, comfort and gearing suited to climbs.
- Fast training rides and racing: assess performance geometry, aerodynamics and components according to the route.
- Your first road bike: look for a bike that suits your body, leaving room in your budget for a helmet, clothing, accessories and maintenance.
Carbon alone does not make a bike more suitable for you. A good aluminium frame with the correct riding position can be a more sensible choice than a prestigious model in the wrong size.
Endurance or aero: which approach suits you?
An endurance bike tends to favour a less tucked position and comfort over long distances. It is worth considering for beginners, as well as those who ride for many hours and want to get home without putting unnecessary strain on their back and hands.
An aero bike aims to reduce air resistance through the shapes of its frame and components. It can suit fast rides, but the benefit also depends on the rider's position and ability to maintain it.
- Do not choose solely by the label: compare geometries and try the riding position.
- Comfort and aerodynamics can coexist: the overall design matters, along with tyres and adjustments.
- For climbing: first check that your gears are low enough for your fitness level.
Disc brakes and gearing: what really makes a difference
Hydraulic disc brakes allow you to control braking with little effort at the levers and deliver consistent performance even in wet conditions. They require checks on pads and rotors and, when necessary, bleeding of the system.
If you are considering a used road bike with conventional brakes, also assess the condition of the rims' braking surfaces. On any bike, tyres and grip on the road surface remain crucial for effective stopping.
- Mechanical groupset: operates the gears using cables and does not require battery charging. It is also a valid choice for those who train regularly.
- Electronic groupset: controls gear changes using buttons and electric motors. It offers light operation, but requires you to keep an eye on battery charge.
- Gear ratios: with the same front chainring, a larger rear sprocket makes pedalling easier. A 50/34 combination with a 11-34 cassette is worth considering for routes with climbs.
Electronic shifting does not assist pedalling: having Di2 or AXS does not make a bike an electric road bike. Assistance requires a model equipped with a dedicated motor and battery.
Size and position: the number on the frame is not enough
Looking for a road bike in size 54 is a starting point, not a guarantee of fit. Two frames labelled 54 can have different lengths and heights.
Height and inside leg measurement help guide your choice, but body proportions, mobility and familiarity with the riding position also need to be considered. Stack and reach describe the frame's vertical and horizontal dimensions respectively relative to the bottom bracket: they are useful for comparing different models.
- Check that you can comfortably reach the shifters and brakes.
- Assess saddle height and setback together with the distance to the handlebar.
- Do not try to compensate for the wrong size with extreme adjustments.
- Before choosing an integrated handlebar, check its width and length: the scope for changes may be more limited than with a separate handlebar and stem.
How much should you invest to move up a level?
A worthwhile investment depends on what is currently limiting you. If you experience pain or tingling after an hour, start with your position; if you struggle on climbs, check your gearing and training before seeking a higher specification.
- Getting started: prioritise size, braking, gearing and a complete set of equipment for riding.
- Improving a bike you are already happy with: consider adjustments and compatible tyres before replacing major components.
- Changing your bike: identify the benefit you want, such as more comfortable geometry, electronic shifting or an aero design.
- Choosing a top-of-the-range bike: compare the complete specification and maintenance costs, without choosing solely for prestige.
When comparing road bike offers, always check the size and specification of your chosen variant. You can explore our collection of road bikes to compare the options.
Used road bikes: what to check
A used road bike can be worth considering if its condition, dimensions and any work needed are clear. Consider the purchase alongside any initial maintenance required.
- Frame and fork: look for signs of impacts, cracks or repairs and ask about the bike's history.
- Drivetrain: have the chain, cassette and chainrings checked for wear.
- Wheels and brakes: check for smooth running, play, wheel trueness and the condition of braking surfaces.
- Electronic components: check operation, batteries and that the necessary charging devices are included.
- Size: rule out an unsuitable size even if the deal looks tempting.

Frequently asked questions
Which road bike should I choose to get started?
Start with the correct size and a comfortable position: endurance geometry is often a good starting point. Prioritise gearing suited to your routes and leave room in your budget for accessories and maintenance.
How do I know if a size 54 road bike is right for me?
The number 54 does not represent the same measurements across all models. Compare the geometry, taking your height, inside leg measurement and body proportions into account, then check your riding position.
Is mechanical or electronic shifting better on a road bike?
Mechanical shifting is a sound choice for getting started and training, with no batteries to recharge. Electronic shifting offers light-action controls and gear changes operated by electric motors, but requires you to keep an eye on the battery charge.
What should I check before buying a used road bike?
Check the size, frame history, any impacts and wear on the drivetrain, wheels and brakes. A workshop inspection helps identify any work needed and assess the purchase as a whole.
