A mountain bike tire in the test for the best gravel tire of 2026? Are gravel bikes really just slowly morphing into MTBs? The 55 mm wide Continental Dubnital is here to answer that question, promising maximum grip on every surface. But what about efficiency, and does this tire even make sense on a gravel bike?

As a fast mountain bike tire, the Continental Dubnital is designed for cross-country racing and downcountry adventures. As the successor to the popular Race King, it aims to strike the ideal balance between grip and efficiency. So is it the perfect fit for our group test? That depends on whether it fits your bike in the first place, because with a claimed width of 55 mm and a measured width of 54.3 mm, the Dubnital is by far the widest tire in the test field – even with the trend towards larger tires, most modern gravel bikes will struggle for clearance. Since our test took place, Continental have also released a 50 mm version, which should be compatible with far more gravel bikes.

Assuming it fits your frame, the tread is meant to impress with a design developed specifically for XC racing. It is primarily optimised for dry to damp conditions on rocky, hard-packed and loose surfaces, which sounds almost tailor-made for the gravel crowd. It is also worth remembering that terrain which you’ll roll over without a second thought on a mountain bike can prove to be too much of a challenge for many gravel bikes. Reinforced, siped centre knobs are designed to provide plenty of traction while keeping efficiency high. In the transition zone, specially reinforced knobs add support for cornering, while the pronounced side knobs are there to deliver maximum grip even in slippery switchbacks. The fast Race carcass helps keep the weight down.

MTB Meets Gravel: Continental Dubnital in the 2026 Gravel Tire Group Test

There is plenty of theory, but how does this mountain bike tire actually perform in our test? Does the gravel competition have anything to worry about? At 618 g, the Dubnital is a little heavier than most of its rivals, but not excessively so. The heaviest model, the Vittoria Terreno Pro T50, weighs a full 700 g. Considering that the gravel tires in this test are on average a whole 10 mm narrower, the weight quickly comes into perspective – if anything, it actually seems surprisingly low.

The Dubnital also impresses when it comes to rolling resistance. At 14.7 watts, it even comes in below the average of just under 15 watts, which is a strong result for an MTB tire of this width. That makes it only just under 4 watts slower than the fastest tire in the entire test, the Schwalbe G-One RS Pro, while promising significantly more traction at the same time. In a direct comparison with the second MTB tire in the test, the Schwalbe Thunder Burt, the Dubnital gives away just under 1.5 watts.

But enough about efficiency; what about its headline strength? Grip is, unsurprisingly, fantastic. Compared with the narrower gravel competition, the Continental Dubnital operates on a different l…
