How to recognize a gravel bike?

A gravel bike stands out for itsar a specific geometry, more comfortable than a road bike and faster than a mountain bike. It allows you to alternate surfaces: paths, roads, trails. Here are some characteristic elements:

  • Frame in aluminum, steel or carbon, sometimes in titanium.

  • Wider tires (35 to 45 mm), often tubeless, with good air volume.

  • Disc brakes for reliable braking.

  • Double or single chainring transmission with a wide speed range.

  • Flared handlebars for more downhill control.

Frame, fork and geometry: the basis of a good gravel bike

The frame and fork form the backbone of the gravel bike. They must be rigid, comfortable, and able to absorb uneven terrain.

  • Complete frame kits (carbon or steel frame + fork).

  • Different geometries depending on use (racing, bikepacking, leisure).

  • Materials selected for their strength: lightweight aluminum, flexible steel, high-performance carbon.

Each frame is selected for its compatibility with modern components (disc brakes, thru axle, 27.2 mm seat post, etc.).

The transmission: the heart of gravel performance

In gravel, the transmission is put to the test. Choosing a suitable, reliable and compatible transmission is essential:

  • Single chainring: simplicity and lightness.

  • Double chainring: more choice of speeds.

  • Cassette wide range (11-42, 10-50…) for optimal versatility.

  • Derailleurs gravel specific: Shimano GRX, SRAM Apex, etc.

We also offer reinforced chains, adapted cranksets (24 mm, 30 mm axle), and all peripheral components such as pulleys, bottom brackets, or oval chainrings.

Disc braking: power and control

Gravel bike braking relies on a disc system (mechanical or hydraulic). There are many advantages:

  • Constant braking whatever the conditions.

  • Better control when descending or on soft terrain.

  • Less wear in intensive use.

Our store allows you to sort and choose according to your level: Shimano G brakesRX RX-810, SRAM Rival, or TRP mechanical systems. We also offer discs, pads, adapters, and levers.

Wheels and tires: contact with the ground

One of the most important components of a gravel bike. Wheels and tires determine comfort, performance, and compatibility with your frame. Our recommendations:

  • Tubeless ready wheels for better performance.

  • Tires Michelin Power Gravel, Hutchinson Overide : perfect for road and path.

  • Tire widths between 38 and 45 mm depending on the practice.

The wheelset is selected based on the axle (QR or thru-axle), internal width (19 to 25 mm), and brake type (centerlock or 6-bolt disc).

Cockpit, handlebars and comfort in bikepacking

A good cockpit provides comfort and precision. On gravel, the handlebars play a fundamental role:

  • Flared handlebars for better grip on descents.

  • Short stems for greater maneuverability.

  • Seatposts with setback or flex depending on your position.

Our store offers you to filter products par material (aluminum, carbon), angle, and diameter. Comfort is essential, so consider adding gel handlebar tape, a suspension seatpost, or an ergonomic saddle.
