The Complete Buying Guide to Gravel Bikes – All You Need to Know

complete buying guide to gravel bikes featured image

One of the newest categories in the cycling industry, gravel bikes truly cater to thrill-seekers (after all, they are also known as “adventure bikes”). These bikes are made to go absolutely anywhere and constructed to stand up to the toughest terrain.

The well thought design of a gravel bike is intended to weather the elements with ease and assure cyclists that they can travel uncharted paths. Also, there is nothing stopping gravel bike owners from enjoying a leisurely Sunday afternoon ride on safe and predictable terrain, too.

These are great all-around bikes for those who favor adventure and need a reliable and dependable everyday bike.

In this article, we will look at the features and characteristics of gravel bikes, what distinguishes them from other types of bikes, and what you should consider when shopping for one, whether at your local bike store or online. We will also share our top choices for gravel bikes to get you started.

The Components of Gravel Bikes

Frames

Gravel bike frames are most commonly made of carbon and aluminum. A smaller number are made of steel or titanium, but chances are you will end up with a carbon gravel bike if you have a higher budget or an aluminum gravel bike if you are on a tighter budget.

Carbon bikes are incredibly lightweight, which is why cyclists favor them. Those interested in speed (and let’s face it: most thrill-seekers are) often prefer a carbon frame.

Because the budget can be one of the most important factors in gravel bike shopping, an aluminum frame presents a solid alternative for those who cannot afford carbon. These frames can save shoppers hundreds of dollars while still giving them a durable and reliable frame that should last for years and stand up to tremendous wear and tear.

Wheels

When shopping for gravel bikes, you will have two-wheel options: 700c wheels or 650b wheels, with the former being the most common.

The best overall performance on gravel bikes is attributed to 700c wheels. They are narrower and usually lighter than 650b wheels, which means they roll faster across most gravel.

Although 700c are more common, this does not mean you should rule out 650b options just yet. A 650b wheel might be the better choice when comfort is a top priority. Perhaps if your identity is nestled somewhere between adrenaline junkie and couch potato, the gravel bike with the 650b wheel could be a better compromise.

The 650b wheel is heavier and rolls slower than the 700c, meaning it will be smoother when crossing obstacles. If you do not want to sacrifice speed or expect that you will only be using your gravel bike on mild terrain, stick with the 700c wheel and tire sets.

Brakes

Even adrenaline junkies need to slow down sometimes, and there is perhaps no more important component in your gravel bike than your brakes. This is an area where you want high functionality and reliability, but you also want a bike that fits your budget. You should never have to sacrifice safety in less expensive bikes.

As you shop for gravel bikes, you will notice two choices regarding brakes: mechanical disc brakes or hydraulic brakes. The former uses a cable system to slow your bike, while the latter uses fluid. Some cyclists prefer hydraulic because they give you more stopping power with less effort than a mechanical disc brake.

Also, hydraulic brakes aren’t affected by mud, and trail debris like disc brakes are. This superior performance comes with a higher price tag, so a good old-fashioned disc brake will have to do if you need a more budget-friendly bike.

Tires

The best tires for your gravel bike will depend on the percentage of time you spend on rough terrain. You might be someone who rides primarily on the roadways with occasional excursions to rough terrain, or perhaps you are shopping for a gravel bike that will, in fact, be used the majority of the time on gravel or other rough paths.

If you are going to use the bike primarily on roads, you can look for a 30 to 32mm tire. If you are splitting your time between smooth pavement surfaces and rough terrain, your bike should have a tire in the 35 to the 38-millimeter range.

Finally, if you are truly staying off the beaten path at all times, and you are the type of cyclist who will be frequenting nothing but uneven terrain like a gravel road, your gravel bike should have a 40-millimeter tire (or wider).

Another important consideration when it comes to tires is upgrading to tubeless ones. This newer technology is ideal for off-road cycling, but it can sometimes be challenging to convert a bike you already own to tubeless tires. We recommend checking with your local bike shop before upgrading.

Drivetrain and Gears

Just as you need to consider the variety of terrain you encounter when it comes to tire choices, you will need to think about this with drivetrain and gears as well.

Gravel bikes are typically going to have two drivetrain options, which are

  • 1x: a single front chainring and fewer gears
  • 2x: two front chainrings and more gears

Some bikers prefer the 1x just because they are simple and lighter in weight. They are fine for use on rolling terrain. But if you are constantly tackling steep climbs, you probably want a 2x drivetrain, which will have an easier gear for your uphill battle.

Suspension

The suspension is not going to be standard in your gravel bike shopping. But this does not mean it does not exist.

If you aim to increase comfort, consider the added suspension features with bikes like the Trek Checkpoint SL 6, Moot Routt, Specialized Diverge Sport, and Cannondale Kingpin.

After all, it is not unreasonable to think that even some adventure-seekers want to experience comfort, too!

Mounts

If you are the type to jump on a gravel bike and just ride where the day takes you, you will definitely need plenty of mounting locations for water, food, and gear. A good gravel bike will offer you multiple mounts to ensure you can carry along all of the essentials you need without being unnecessarily weighed down.

Gravel Bikes Compared to Other Bikes

If you are new to adventure bikes, you may find yourself overwhelmed by all of the choices. Unless you are an avid cyclist, you might be the person who thinks, “aren’t all bikes pretty much the same?”

This would be akin to thinking all motor vehicles are ultimately the same. However, we know that there is a world of difference between a compact hybrid car and a gas-guzzling “monster” truck. The world of cycling also has a vast array of choices, meeting every need from a triathlon to a leisurely Sunday afternoon pedal at the beach.

When shopping in the niche category of gravel bikes, you may wonder about the overlap and differences between road and cyclocross bikes, and we will take a look at that here, in three sections: frames, mounts, and tires.

  • Frames: Gravel bikes will have lower and longer frames to give riders more stability during a long descent. A cyclocross bike will have higher bottom brackets to clear obstacles.
  • Mounts: Gravel bikes will have more mounts than road or cyclocross bikes, built with the expectation that a cyclist on a gravel bike may be out in longer stretches without places to stop. Therefore, she will need more gear mounted on the bike to eat and stay hydrated along the way.
  • Tires: Gravel bikes may come with 45mm or even 50mm tires instead of the 30mm road bikes or 40mm cyclocross bikes. These tires are certainly heavier, but they are needed on bumpy pathways.

But I Already Have a Mountain Bike – Do I Need a Gravel Bike?

A mountain bike will do the job if you are an adventure seeker, and we are not suggesting you need to get rid of it just because a niche category now exists.

However, some cyclists might prefer the fact that a true gravel bike will be significantly lighter than a mountain bike and will also offer more mounts. In this way, a gravel bike is a better choice for those who are likely to split their time between pavement and gravel.
