Differences between gravel bikes and racing bikes: the seven fundamental points
The differences between gravel bikes and road bikes can be analyzed through several perspectives, which include frame geometry, tires, frame construction materials, accessory mounting points, finishing kit and other features.
Frame Geometry: Gravel bikes tend to have a longer, lower, and slower geometry than road bikes. That's because gravel riding requires more stability and ability on technical terrain, while road bikes place a premium on precise handling and responsive speed.
Tires and clearance: Road bikes usually fit narrower tires, while gravel bikes can accommodate wider tires, up to 35mm or more. The distance between the tires and the frame stays is wider in gravel to allow the use of wider tires and to facilitate the removal of mud and the fitting of mudguards.
Frame materials: Both types of bicycles can be made of aluminum, carbon, steel or titanium. Steel is more common in gravel for its strength and comfort, while carbon remains popular for high-end bikes in both categories.
Accessory mounting points: Road bikes tend to have fewer accessory mounting points than gravel bikes. Gravel bikes, especially those geared towards bikepacking, can be equipped with mounts for mudguards, racks and other equipment.
Finishing kit: Road bikes are often equipped with aerodynamic and lightweight components to maximize efficiency. Gravel bikes may feature flared handlebars for a wider, more stable stance, suspension seatposts, and other features to improve comfort and ability on technical terrain.
Suspension: Some gravel bikes may have suspension built into the frame or components to better absorb shock on uneven terrain. This feature, although less common on road bicycles, can be present on endurance models.
Pedals: Road cyclists tend to prefer road bike pedals, while gravel cyclists may opt for SPD-style MTB pedals for added convenience on technical terrain.
Gravel bikes offer greater versatility to tackle a variety of terrains, including dirt trails and unpaved roads, while road bikes are optimized for efficiency on smooth asphalt. However, many gravel bikes can be adapted for road use by replacing tires and other components. The choice between a gravel bike and a road bike depends on the rider's personal preferences and expected riding conditions.
