Gravel bikes: how to choose the right one

Updated on 22 October 2026. Recommended products are available at the time of the update.

To choose the right gravel bike, start with the routes you will ride: how much tarmac, how much off-road terrain and how many hours you want to spend in the saddle. Then compare size, geometry, gearing and tyre clearance: even when looking for a gravel bike on offer, these are the factors that make the purchase right for you.

What is a gravel bike for compared with a road bike?

A gravel bike lets you alternate between tarmac, gravel roads and off-road tracks on the same bike. Compared with a road bike designed for tarmac, it generally offers clearance for wider tyres and features designed for riding on uneven surfaces.

Drop handlebars offer several hand positions, but that does not make all gravel bikes the same. Some prioritise racing, others long rides or trips with bags.

• Tarmac and gravel roads: a gravel bike is a versatile choice for changing your route during a ride.
• Tarmac only and a focus on speed: a road bike may be more suitable.
• Very technical trails, roots and steps: consider a mountain bike, especially if you want more control on rough terrain.

How to choose

Aluminium or carbon frame?

Aluminium is a good starting point if you want a practical gravel bike and would like to allocate part of your budget to components and accessories too. A bike with an aluminium frame may also have a carbon fork: check the two materials separately.

Carbon allows frames to be designed with different weight, stiffness and flexibility characteristics. However, on its own it does not guarantee a more comfortable bike: riding position, tyres and pressure have a major influence.

• To get started: consider an aluminium bike in the correct size with gearing suited to your routes.
• For sports riding: compare the complete design, looking beyond the frame material.
• For touring: check the mounts for bags and racks and the stated load limits.

1x or 2x groupset: what is the difference?

A 1x groupset has a single chainring at the front: you only need to operate the rear derailleur. A 2x has two chainrings and can offer smaller steps between gears, useful for maintaining your rhythm on tarmac.

How easy climbing feels depends on the combination of chainring and largest sprocket, not just the number of speeds. A single-chainring setup does not automatically offer easier gearing than a double.

• 1x: suitable if you want simple controls and frequently alternate between surfaces and gradients.
• 2x: worth considering if you ride a lot on tarmac and want to fine-tune your pedalling cadence.
• Climbing with luggage: compare the lowest gear available on each build.

Wheels, tyres and tyre clearance

The tyre fitted and the maximum permitted width are two different specifications. A bike sold with 40 mm tyres might accept wider ones, but this needs confirmation in the technical specifications.

• Tarmac and firm off-road surfaces: look for a fast-rolling tread suited to the surface.
• Gravel and rough sections: consider greater volume and more pronounced tread, within the permitted limits.
• Tyre clearance: observe the frame and fork limits and allow the space needed for mud and mudguards.
• Tubeless: check rim and tyre compatibility. The wording tubeless ready does not necessarily mean the bike is already set up without inner tubes.

Pressure should be adjusted according to total weight, surface, tyre and rim. Always inflating to the maximum can compromise comfort and grip.

Endurance or race geometry?

Endurance geometry prioritises a position you can maintain on long rides. A gravel race bike focuses on performance and may require a more tucked position: it needs to suit your mobility and riding style.

Compare the height and length of the riding position, including the geometry's stack and reach measurements. The size label alone is not enough.

Size, handlebars and levers

A size S gravel bike does not necessarily have the same measurements across different brands. Height and inside leg measurement help guide your choice, but your torso, arms and desired position also need to be considered.

Try reaching the brake levers from the different hand positions on the handlebars. Handlebar width, lever reach and stem length should allow you to brake and steer with control.

Gravel bikes on offer: how to assess your purchase

To compare gravel bike offers, compare equivalent builds and sizes side by side. Two aluminium bikes can differ considerably in their fork, drivetrain, brakes and wheels.

• Size: avoid adapting to an unsuitable frame just because the offer looks appealing.
• Brakes: distinguish between cable-operated mechanical disc brakes and hydraulic disc brakes.
• Build: check the components and gearing of the specific version.
• Included equipment: check whether pedals and necessary accessories are included.
• Future use: consider tyre clearance and mounts before planning changes.

You can compare models in the Gravel Bikes collection. For shipping information, see the dedicated page.

Frequently asked questions

What is the difference between a gravel bike and a road bike?

A gravel bike is designed for riding on both tarmac and unpaved roads and generally offers clearance for wider tyres. A road bike designed for tarmac prioritises efficiency on the road.

Is aluminium or carbon better for getting started with gravel riding?

Aluminium is a practical choice for getting started, especially if it allows you to buy a well-equipped bike in the right size. Carbon should be assessed as part of the overall bike design: comfort and handling also depend on geometry, tyres and riding position.

Is a single or double chainring drivetrain better on a gravel bike?

A single chainring simplifies gear shifting; a double chainring can offer closer gear ratios, which are useful on tarmac. For climbing, always compare the chainring and largest sprocket on each build.

What should you check before buying a gravel bike on sale?

Check the size and geometry first, then the gearing, brake type and tyre clearance. Compare the exact build and check which accessories are included.
