Gravel bikes: how to choose the right one

Updated on 26 October 2026. The recommended products are available at the time of this update.

To choose the right gravel bike, start with your routes: how much tarmac, how much off-road riding and how many hours you want to spend in the saddle. Then compare size, geometry, gearing and tyre clearance: even a gravel bike on sale is only a good buy if it meets these needs.

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

A gravel bike lets you link tarmac, gravel roads and off-road tracks on a single bike. The drop handlebar resembles that of a road bike, but you generally get more tyre clearance and features designed for control on uneven surfaces.

  • Choose a gravel bike if you want to ride different surfaces on the same outing, explore back roads or plan trips with bags, checking which mounts are available.
  • Consider a road bike if you ride mainly on tarmac and want efficiency and speed on that surface.
  • Consider the route's limitations: a gravel bike does not automatically make jumps, very rough descents or technical mountain bike trails suitable to ride.

How to choose

Aluminium or carbon frame

Aluminium is a practical choice for getting started, training and touring. Many builds pair it with a carbon fork: always assess the complete bike, looking beyond the frame material.

Carbon allows weight and structural behaviour to be tailored, but does not guarantee a more comfortable bike on its own. Riding position, tyres and pressure have a considerable effect on comfort; comparing weight requires figures for comparable sizes and builds.

1x or 2x groupset: what really changes

  • Single chainring 1x: just one chainring at the front, with no front derailleur to operate. It is practical if you want simple shifting, but some cassettes have bigger jumps between gears.
  • Double chainring 2x: generally offers more options for finding the right cadence, especially when alternating between fast tarmac riding and climbs. You also need to operate the front derailleur.
  • For climbs and luggage: check the lowest gear, not just the number of speeds. With the same chainring, a larger rear sprocket makes pedalling easier.

For example, a 40-tooth chainring with a 11-44 cassette does not offer the same lowest gear as a 40 chainring with 11-50. Choose according to the gradients you ride and the load you expect to carry.

Wheels, tyres and tyre clearance

The size of the fitted tyres and the maximum permitted tyre clearance are two different figures. A bike supplied with 40 mm tyres might accommodate wider ones, but this must be stated for that model.

  • Tarmac and firm off-road surfaces: consider a fast-rolling tread and a width suited to the surface.
  • Gravel and uneven terrain: more volume can help with comfort and grip, with pressure suited to weight, tyre and rim.
  • Tyre clearance: respect the frame and fork limits, leaving the required space for mud too.
  • Wheels: check compatibility between rim width and tyre. The Tubeless Ready designation indicates compatibility, but does not confirm that the bike is already set up without inner tubes.

Endurance or race geometry

Endurance geometry prioritises a position you can maintain on long rides. Race geometry is aimed at competitive riding and may require a more tucked, demanding position.

To compare them, look at stack and reach: these indicate the frame's height and forward extent at the head tube. Marketing labels help you find your way, but your choice needs to be checked against your proportions and mobility.

Size and levers: control starts with your hands

A size S gravel bike does not have the same measurements across all brands. Height and inside leg measurement are a starting point, to be considered alongside torso length, arm length and your preferred position.

Check that you can comfortably reach the brake levers from both the hoods and the drops. Lever reach adjustment, where available, and the correct handlebar width can improve control.

Gravel bikes on sale: what to compare

If you are looking for an aluminium gravel bike on sale, compare bikes with similar equipment. Fork material, drivetrain, brakes, wheels and luggage mounts can make a big difference to how useful the build is for you.

  • Check the size first: a bargain in the wrong size is still a poor fit.
  • Read the full specification, as the groupset name may refer to only some components.
  • Check the stated tyre clearance and the mounts needed for bags, mudguards or racks.
  • Consider any changes needed to adapt your position and gearing to your routes.

You can compare the options in the Gravel Bikes collection. For shipping information, see the shipping policy.

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 surfaces, generally with more tyre clearance and handling suited to uneven terrain. A road bike prioritises efficiency on tarmac.

Is an aluminium or carbon frame better for a gravel bike?

Aluminium is a practical choice for getting started and for many uses, while carbon allows weight and frame behaviour to be tailored. Comfort and ride quality also depend on geometry, riding position and tyres.

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

A single chainring simplifies shifting; a double generally offers more options for finding your preferred cadence. For climbs, always check the chainring and cassette, because the number of speeds alone does not indicate how easy the lowest gear is to pedal.

How can you tell whether a gravel bike on offer is good value?

Compare the size, fork, gearing, brakes, wheels and tyre clearance with those of similar builds. Also consider any changes needed: a bike that already suits your routes and riding position is a more sensible choice.
