Wide tyre clearance has become one of the defining features of modern gravel bikes. Not because every rider needs massive tyres, but because clearance for MTB tyres gives you the freedom to choose the tyres that best suit your riding.

Only a few years ago, a frame that accepted 45mm tyres was considered generous. Today, many manufacturers are designing gravel bikes around 50mm tyres, while an increasing number of models officially accommodate 57mm (2.25in) mountain bike tyres.

Part of the reason is that lightweight XC mountain bike tyres have become increasingly common in gravel racing. Riders tackling long, technical events have discovered that wider tyres can provide a faster overall package than narrower gravel tyres. Meanwhile, adventure riders have embraced larger tyres because they open the door to rougher tracks and more remote backcountry routes.

In this article, I’ve compiled a comprehensive list of 30+ performance-oriented gravel bikes that officially accept tyres measuring 57mm (2.25″) or wider. These bikes prioritise lower riding positions, racier geometries and lighter-weight builds. A separate article will cover more adventure-focused gravel bikes with taller front ends, more relaxed handling and features better suited to long-distance exploration.

Let’s get into it!

Why Wider Tyres Can Be Faster

Tyres influence the ride quality of a bike more than almost any other component. A simple tyre change can transform comfort, grip, impact protection and even speed.

Over the years, I’ve steadily increased the tyre widths I ride, and each step has felt like an upgrade. Larger tyres have consistently improved comfort and grip while bringing surprisingly little penalty on the road. I’ve most recently been testing Schwalbe G-One RX Pro gravel tyres in a 60mm width, and the combination of comfort and speed has cemented my belief that the trend toward wider tyres is well justified.

At first glance, it seems counterintuitive that a tyre approaching mountain bike dimensions could roll as efficiently as a much narrower gravel tyre. The explanation, however, isn’t simply the width of the tyre itself.

Many wide tyres use lighter, more supple casings because their larger air volume provides greater protection against impacts and pinch flats. This means they can sometimes achieve lower rolling resistance than narrower gravel tyres that rely on thicker, heavier casings for durability.

You can see this trend in the rolling resistance data from John Karrasch’s CRR Testing Database. His outdoor rolling resistance testing shows that wider tyres tend to perform better than narrower ones. On smoother “Cat 1″ gravel, eight of the ten fastest tyres tested are wider than 53mm (2.1”). That increases to nine out of ten on “Cat 2” gravel, while every tyre in the top ten on the rougher “Cat 3” surface is wider than 53mm.

There is, of course, a limit on tyre width. Not everyone benefits from maximum tyre volume. Eventually, wider tyres become heavy enough that the additional weight, rolling resistance, and aerodynamic drag outweigh the gains in efficiency. Exactly where that tipping point lies depends on the gravel surface, riding speed, rider weight and much more.

The Trade-Offs of Wide Tyre Clearance

There are a few compromises to be aware of when it comes to gravel bikes with wide tyre clearance.

The first is that you will generally be limited to a 1X drivetrain. This is already the default choice on most modern gravel bikes, so it will only matter to some.

With a very wide rear tyre, there is limited room around the chainstays, seatstays and chainring area for a front derailleur, and this forces manufacturers to design their bikes for 1X only. Some frames do still allow a front derailleur, but in those cases, the maximum tyre clearance drops to around 45 to 48mm at the rear.

The second compromise is a slightly wider crankset q-factor. To create enough space for larger tyres, manufacturers typically increase the spindle width by a total of 5mm. This results in a wider stance, which some people don’t like the feel of. A road crankset with a 145mm Q-factor becomes 150mm on a gravel bike with wide tyre clearance. It’s not a lot, but it may matter if you’re sensitive to crankset dimensions.

The final consideration is that these bikes often have a minimum tyre size of around 45mm. This is because the frames are designed around larger-diameter tyres, so manufacturers will typically increase the bottom bracket drop to keep the rider’s centre of gravity lower and maintain appropriate handling.

Installing a significantly narrower tyre can lower the bottom bracket height by too much. This can leave the pedals closer to the ground, increasing the risk of pedal strikes when cornering.

Why Tyre Clearance Matters When Buying a Gravel Bike

Given how much tyres influence a bike’s speed, comfort and capability, I’d always lean toward choosing a frame with a little extra clearance. The compromises will be small to most riders, but the range of possibilities it opens up is substantial.

The advantage of a gravel bike with generous tyre clearance is the flexibility it provides. As your riding evolves, you might find yourself exploring rougher roads, tackling more technical trails or heading further off the beaten track. In those situations, fitting larger tyres can significantly expand what your bike is capable of without replacing the frame.

Conversely, a bike limited to 45mm clearance gives you much less room to adapt if your preferences change. If you eventually decide you need more tyre volume, upgrading may require replacing the frame entirely.
