Gravel Bikes

Gravel Bikes

Gravel bikes have gained significant popularity as a versatile option for adventure, exercise, racing, and exploration on various types of terrain, including paved and unpaved surfaces. Compared to road bikes, gravel bikes offer more versatility and capability for off-pavement riding. Here are the key points to know about gravel bikes:

A gravel bike is a bicycle designed for covering long distances over a wide variety of terrains. It typically features a drop handlebar, wider tires (35 mm and up), disc brakes, and a longer wheelbase for stability.

Finding the Right Size

Gravel bikes come in different frame sizes, usually expressed in centimeters or XS to XL size range. It's important to choose the right frame size for your body to ensure comfort and optimal handling. Manufacturers provide size guidelines based on height, but an experienced bike salesperson can help you find the best fit. You can also compare the reach and stack measurements on a geometry chart to find a similar fit to your current bike.

Types of Riding

Gravel bikes cater to different types of riders, including fitness enthusiasts, adventure riders, and competitive or non-competitive event riders. They are suitable for riding on unpaved surfaces like dirt or gravel roads, 4x4 tracks, and smooth singletrack. They are also used for bikepacking, which involves carrying gear on the bike for multiday tours.

Frame Materials

Gravel bikes are commonly made from aluminum, carbon fiber, or steel. Aluminum frames offer a smooth ride at a lower cost, while carbon fiber frames provide a more comfortable and lightweight option. Steel frames are heavier but offer the smoothest and most vibration-absorbing ride.

Geometry and Frames

Gravel bike geometry can vary, with some models resembling road bikes and others resembling mountain bikes. Road-oriented gravel bikes have quicker and more nimble handling, while those closer to mountain bikes offer stability at high speeds and capability on rough terrains. The frame can accommodate either 700c (road bike diameter) or 650b (27.5-inch diameter) wheels.

Tire Clearance and Wheels

Gravel bike tires are wider than road bike tires but narrower than mountain bike tires. They typically range from 32 mm to 50 mm wide for 700c wheels and up to 54 mm wide for 650b wheels. Tire clearance is an important consideration, as it determines the maximum width of tires the bike can accommodate. Wider tires provide better traction and durability on rough terrain.

Gearing

Gravel bikes can come with either a 1x (one-by) or 2x (two-by) drivetrain. A 1x drivetrain features a single chainring in the front and a wider range of gears in the cassette. It simplifies shifting and provides better chain retention on rough surfaces. A 2x drivetrain has two chainrings in the front and offers more gear combinations, suitable for varied terrains and heavy loads.

Brakes

Gravel bikes are equipped with disc brakes, which offer superior stopping power and all-weather performance compared to rim brakes. Disc brakes can be hydraulic or cable-actuated. Hydraulic disc brakes provide stronger and more progressive braking with less finger effort, while cable-actuated brakes are more affordable and easier to service.

Frame Mounts

Gravel bikes often include additional mounts for accessories like extra water bottle cages, frame bags, and racks. These mounts allow riders to be self-supported during long rides or bikepacking trips. Race-oriented models may have minimal attachment points, so consider your riding needs before choosing a bike.

Remember, while this information serves as a starting point, it's always recommended to consult with a knowledgeable bike specialist at a reputable bike shop
