    What makes a gravel bike stand out from other bikes?

    Gravel bikes have become a favorite among cyclists for their versatility and adaptability.

    • Geometry: Gravel bikes are much more upright and relaxed to ride. 
    • Tires: Gravel bike tires are much wider and have lower pressures.
    • Wheels: Come in two sizes and have a wider rim.
    • Brakes: More powerful and better in off-road conditions.
    • Gearing: Much lower ratios with clutch support.
    • Finishing kit: Different sizes and also handlebars are flared.

    The answer lies in the specialized gravel bike components that are uniquely designed for mixed-terrain adventures. Let’s delve into these essential parts and understand how they contribute to the overall performance of a gravel bike.

    Are gravel bike components much different from other bikes?

    Although components of a gravel bike may look similar to mountain bike and road bike components, they are different in their own subtle way. They are a mix of the technology of road bikes and mountain bikes and the best gravel bike components give you a great experience no matter what terrain you are on. The best gravel bike components are those that offer durability, comfort, and versatility, making your ride smooth and enjoyable, no matter where you go.

    The importance of gravel bike frames and forks as major gravel bike components

    The first part of a gravel bike to discuss is the frame and forks. This is where all the other components attach and where the rider stays in control.

    Gravel bike frame materials and design

    The gravel bike frame bike parts

    The frame on a gravel bike is generally made of steel, aluminum, or carbon fiber. They are designed similarly to road bikes but with a more relaxed geometry and a wider tire clearance. It’s not rare to see the off-gravel bike even look like a mountain bike frame with rigid forks. They are generally longer than a typical bike to increase stability on rough roads. 

    Gravel bike forks types

    When it comes to forks, they are generally rigid but some gravel bikes in modern times are using some form of suspension whether it be inside the frame or actual suspension front forks altogether.

    Finding the balance between speed, ability, and durability is the key to a gravel bike frame. When it comes to manufacturers, there’s no right or wrong for gravel bikes. It’s all about what they think would work on a gravel road, a trail, or the tarmac.

    Gravel bike gearing: gravel bike parts designed for versatility

    Next, we come to gearing. You will see many gravel bikes with road bike gearing on, but this is changing, as companies now use dedicated gravel groupsets such as the Shimano GRX or the Campagnolo Ekar. These are the best gravel bike components for gearing.

    1X drivetrains and clutch mechanisms:

    Gravel bike gearing is generally much lower for off-road terrain and short, steep hills. They often use a 1X like a mountain bike to keep it simple and improve their ability to perform off-road. You will also find they often use a clutch mechanism in the rear derailleur so the chain doesn’t fall off. 

    Although packed with mountain bike technology, they still use a shifter like a road bike. So you get the road bike feel with the mountain bike ability, making it the perfect gearing for mixed-terrain riding. 

    Gravel bike wheels and tires: gravel bike components built for all terrain

    Wheel sizes and durability

    Gravel bike wheels are a mix of road and mountain bike wheels. They come in two different sizes. 700c is the same as a road bike wheel, and 650b, which is equivalent to a 27.5” mountain bike wheel. The larger wheels are better at rolling over obstacles, and the smaller wheels for working around them.

    Wheel Size

    Equivalent Bike Wheel

    Advantages

    Internal Width

    700c

    Road Bike Wheel

    Better at rolling over obstacles

    19mm to 25mm

    650b

    27.5" MTB Wheel

    Better at maneuvering around obstacles

    19mm to 25mm

    The difference isn’t in diameter but in the internal width of the wheel, which is roughly 19mm to 25mm. This means it suits larger tires better and offers much more durability against knocks and bangs. As far as components of a gravel bike go these are much more unique than people first think.

    Gravel bike tire design

    Tires on gravel bikes are not like those on road or mountain bikes. They are not these big, rough, grippy MTB versions or skinny road slicks. They are a mix of both in that they have extra width from 35c to 52c but also come with a slick center and rough, small, grippy knobbles on the outside. 

    They are great for riding on the road and for having good off-road ability. They are ideal tires for all surfaces, and on gravel, they are the fastest option by far. Bigger tires also offer a huge amount of comfort for the rider. They can be run at lower pressure and are often tubeless, which means they are filled with sealant and can self-repair. 

    Gravel bike parts for control and comfort: handlebars, stems and seats

    When it comes to gravel bikes, the handlebar and stem are very different from what you might think.

    Flared handlebars

    Gravel bikes mainly use a drop-style bar like a road bike, but they are what you call flared

    Gravel bikes mainly use a drop-style bar like a road bike, but they are what you call flared. Flared means they are bent at the bottom, so when in the drops, you have more control.

    Shorter stems

    The stems on gravel bikes are also generally shorter.

    The stems on gravel bikes are also generally shorter. Instead of the 90mm to 120mm on a road bike or the 40mm to 60mm on a mountain bike, they are around 60mm to 90mm. This helps the bike feel controlled but agile at the same time.

    Seat and Seatpost

    Gravel bike seats are generally made with a little more padding and often push the pressure points toward the seat bones instead of on the undercarriage. This is to add extra comfort and prevent bumps from getting to the behind.

    The seat posts are fairly standard. You typically see most made of aluminum compared to carbon fiber equivalents on road bikes. You also find that dropper posts are not really done on gravel bikes due to not often needing them.

    What gravel bike parts to upgrade first?

    Upgrading your gravel bike components can significantly enhance your riding experience, whether you're looking for better performance, comfort, or durability. Here’s where to start:

    Upgrade your gravel bike wheels and tires for better performance

    main gravel bike parts
    One good upgrade is to choose a set with a wider rim and better spoke quality

    One of the most impactful upgrades you can make on your gravel bike is to the wheels and tires. Opt for a wheelset with a wider internal rim width and a durable build that can withstand rough terrain. Pair these with high-quality, tubeless gravel tires that offer the right balance of grip and rolling resistance for your preferred terrain. This upgrade will improve both your bike's handling and overall ride quality.

    Enhance comfort with a new gravel bike handlebar and seat

    For improved comfort, consider upgrading your handlebars and seat. A flared handlebar provides better control and a more comfortable position during long rides. Meanwhile, investing in a more cushioned, ergonomically designed seat can make a world of difference on extended adventures. These upgrades not only make your rides more enjoyable but also help prevent fatigue and discomfort over long distances.

    Can a gravel bike replace all my bikes?

    Gravel bikes are amazing and perfect for many different types of riding. Many riders choose this option because it saves money and allows them to invest more in a single bike instead of many bikes. 

    Gravel bikes are the most efficient at gravel riding and on mixed terrain. They will never be as quick as a road bike when it comes to road riding. They are good at off-road riding but will never give the comfort and ability of a mountain bike.

    It's good to understand that gravel bikes have a place, but they can not outperform other bikes in their own disciplines.

    Gravel bike accessories: customizing your ride

    When it comes to accessories, gravel bikes have a lot. You get frame bags for carrying extra goods, rear racks, front racks, top tube bags, and even saddlebags for adventure. You can also add suspension stems or seat posts. 

    Many riders also go with aero bars, especially if they are planning longer trips. Not only do you get an extra position, but you also have a place to hang extra goods if required. Standard accessories such as bottles, cages, lighting, and much more are also available.
