Enter the Gravel Tire

Gravel tires are purpose-built for rough, mixed surfaces. The key features of gravel tires to consider are:

• Tire Width: 

Gravel tires are wider than road tires, typically ranging from 32mm to 45mm or more. This extra width provides stability and allows lower tire pressure for improved grip on loose surfaces.

• Casing and Puncture Protection:

Gravel tires often have reinforced casings and puncture protection layers to withstand the rigors of off-road riding.

Tubeless Consideration

Many gravel cyclists prefer tubeless setups. Tubeless tires can run at lower pressures, further enhancing traction and reducing the risk of pinch flats. Additionally, they can self-seal small punctures, keeping you rolling on your gravel adventures.

Tire Pressure Matters

Gravel riding often involves varying terrain, from smooth gravel roads to rough and rocky sections. Experiment with tire pressures to find the right balance between grip, comfort, and efficiency. Lower pressures provide more traction but may increase rolling resistance.

The Limitations of Rim Brakes

Rim brakes, commonly found on road bikes, rely on calipers that grip the wheel’s rim to provide stopping power.

• Wider Tire Clearance: 

Gravel bikes can use larger tires, but rim brakes may not accommodate wider tires.

• Rim Wear: 

Aggressive braking on rough terrain can accelerate rim wear, potentially compromising the integrity of your wheels.

The Advantages of Disc Brakes

Disc brakes, on the other hand, offer several advantages that make them ideal for gravel biking:

• All-Weather Performance: 

Disc brakes perform consistently in all weather conditions, including rain, mud, and snow.

• Wider Tire harmony: 

Disc brakes let you use wider, knobbier tires for better grip on gravel, thanks to their increased tyre clearance.

Conversion Process

Converting from rim to disc brakes is a significant upgrade that involves several key steps:

• Frame and Fork harmony: 

Ensure your bike’s frame and fork have the necessary mounts for disc brake calipers. Some older road bikes may require alteration or may not be suitable for conversion.

• Brake Calipers: 

Select the appropriate disc brake calipers (mechanical or hydraulic) and mount them securely on your bike. Ensure proper alignment for effective braking.

• Brake Levers: 

Replace your current brake levers with compatible disc brake levers. Hydraulic disc brakes require hydraulic brake levers.

• Cabling and Hydraulics: 

Ensure proper installation of the necessary cabling or hydraulic lines, routing and bleeding them for hydraulic systems.

Wheel Diameter

Gravel bikes typically come in two-wheel diameters: 700c and 650b (27.5 inches). Each has its advantages:

• 700c Wheels: 

These are similar to standard road bike wheels, offering higher rolling speeds. They perform well on smoother gravel surfaces and for riders who prioritize speed.

• 650b Wheels: 

These smaller wheels provide additional tire clearance and improved stability on rough and technical terrain. Many people often prefer them for their ability to tackle more challenging gravel routes.

Hub harmony

Consider the harmony of the wheelset’s hubs with your bike’s drivetrain. Ensure that the hub you choose is compatible with your cassette type, such as Shimano, SRAM, or Campagnolo. Additionally, make sure it also aligns with your axle standards, which could be quick-release or thru-axle.

Handlebar Swaps: Finding the Perfect Gravel Handlebars

The Importance of Handlebars

They are your primary point of contact with the bike and play a pivotal role in:

• Control: 

The right handlebars provide stable and responsive steering, essential for navigating gravel’s ever-changing terrain.

• Comfort: 

Handlebars affect your riding posture and comfort. The wrong choice can lead to discomfort on long rides.

• Flexibility: 

Gravel biking encompasses a wide range of terrains, from smooth gravel roads to technical trails. Your handlebars should be versatile enough to handle this diversity.

Common Gravel Handlebar Types

Gravel bikers can choose different handlebars. Each type offers unique advantages and suits different riding styles:

• Drop Bars: 

Bike drop bars have various hand positions for easier riding on smooth areas and better control on tough terrain.

• Flared Drop Bars: 

These drop bars have wider drops, providing more stability and control on descents and technical terrain. They offer a compromise between traditional drop bars and flat bars.

• Flat Bars: 

Widely used in mountain biking, flat bars offer an upright riding position and precise control. They are ideal for technical trails but may have limited hand positions.

• Aero Bars: 

To improve fluid dynamics on long gravel rides, riders can add aero bars to drop bars. This will help them achieve a lower and more streamlined position.

Assessing Your Riding Style

Your gravel handlebar choice should align with your preferred riding style:

• Long-Distance Touring: 

If you plan on covering significant distances, drop bars or flared drop bars provide multiple hand positions, reducing fatigue.

• Speed and fluid dynamics: 

For faster riding on smooth gravel roads, riders can add aero bars or extensions to their drop bars.

Gearing for Gravel: Optimizing Your Drivetrain

The Role of Gearing in Gravel Biking

Gearing plays a pivotal role in how efficiently and comfortably you navigate gravel terrains. Here’s what you need to consider:

• Climbing Power: 

Gravel routes often feature challenging climbs. Having low enough gears allows you to tackle steep ascents without excessive effort.

• Top-End Speed: 

For flatter or smoother sections, higher gears enable you to reach and maintain higher speeds.

• Terrain flexibility: 

Gravel biking involves a mix of terrains, from smooth gravel roads to technical trails. Your gearing should be versatile enough to handle this diversity.

Drivetrain Components to Consider

To optimize your gravel drivetrain, you should focus on the following components:

• Cassette: 

The cassette consists of multiple cogs at the rear wheel. Choose a cassette that provides a range of gears suitable for both climbing and maintaining speed on flat sections.
