How to Choose a Gravel Bike

Where do you plan to ride?
A gravel bike is perfect if you plan to ride unpaved surfaces like dirt or gravel roads and paved roads to get there.

Consider your tires
Tires are often treaded or knobby for durability and traction. Wider tires are more capable of handling rougher, looser terrain; skinnier tires are ideal for smooth, hardpacked surfaces.

Get the correct frame size
Frame sizes may be expressed in the length of the seat tube or XS through XL size range. Consult that bike's sizing chart.
