Additionally, the narrow-wide chainring design provides better chain retention on rough roads. Many riders prefer 1x because it simplifies shifting by eliminating the front derailleur. Single-chainring (1x) drivetrain technology originated in mountain biking and has become increasingly popular among gravel riders. Gravel bikes, on the other hand, commonly use a 1x drivetrain. This allows for a smoother transition between gears, making it easier for riders to maintain a comfortable pedaling cadence at speed. The larger outer chainring is for achieving high top speeds on flat terrain, while the smaller inner chainring is for climbing steep hills.īecause road riding is typically faster, road bike cassettes have a tighter gear range with more 1-tooth steps between gears. Road bike gearing setup is typically a 2x drivetrain with two chainrings. However, if you plan to ride on rough terrain and need more low-end gearing for climbing a 1x or 2x gravel drivetrain may be a better option. If you primarily ride on smooth roads and want to maximize speed and efficiency, a 2x road drivetrain may be the better choice. These gravel bikes are for competitive gravel racing, where speed and efficiency are paramount, and riders must navigate quickly and confidently through various terrain. Some gravel race bikes, such as the Cervelo Aspero 5, have more aggressive geometry similar to road bikes, with a more aerodynamic riding position and greater emphasis on speed and agility. Gravel bikes also have wider tires and a higher stack height, contributing to a more stable and comfortable ride on unpaved roads. This design places the rider in a more upright position, which is more comfortable for long rides and allows for better visibility on rough terrain. The lower bottom bracket, slacker head angle, and longer wheelbase are all intended to make the bike more stable on rough terrain, which can be unpredictable and require quick and sudden changes in direction. Gravel bikes have a higher stack height, a shorter top tube, a taller head tube, and slacker head and seat tube angles. This design places the rider in a more aerodynamic position, with more weight over the front wheel for improved handling at high speeds. The steeper head angle and shorter wheelbase also contribute to agile handling, ideal for navigating sharp turns and cornering at high speeds. Road bikes have a longer top tube, shorter head tube, lower stack height, and steeper head and seat tube angles. Road bike geometry is lower and more aggressive The most noticeable difference between a road and a gravel bike is the frame geometry. Overview of road and gravel bike characteristics Tend to be heavier due to prioritizing durability, stability, and capability to handle rough terrains Generally lighter due to prioritizing aerodynamics and weight savings More comfortable on rough terrains due to wider tires and more flexible frames Wider, more durable tires for better traction on various surfaces (size varies greatly depending on the model and intended use).Īerodynamic components, narrower handlebars for lower, more streamlined riding positionsįlared handlebars for better off-road control, extra frame mounts for gear, and more durable componentsĬan be comfortable on smooth roads endurance models offer more comfort with special shock-absorbing technologies Narrower, lightweight tires for speed (usually 23-32mm wide) Both setups provide more low-end gearing for steep climbs 1x simplifies shifting and improves chain retention.
