Continental Dubnital 29x2.40 Tubeless Mountain Bike Tyre — Rapid Race Compound, E25 E-Bike Reinforced

The Continental Dubnital is a tubeless-ready 29x2.40 mountain bike tire built to deliver high-speed traction and low rolling resistance on hardpack, rocky and mixed dry-to-damp trails.

Engineered as the successor to the Race King, the Dubnital blends a lightweight, race-oriented casing with a fast compound and dependable trail grip. Its construction balances suppleness for traction with reinforced elements to resist punctures and premature wear—making it suitable for aggressive cross-country and down-country riding. This E25-rated version adds structural reinforcement for e-bikes, so it tolerates the extra torque and sustained speeds common on motor-assisted trails.

How does the Dubnital perform on hardpack and rocky terrain?

On compact dirt and rocky lines the Dubnital prioritizes speed without sacrificing predictable cornering. The tread pattern sheds small pebbles while delivering consistent contact and bite, which helps maintain momentum through flats and technical sections.

• Rapid compound for reduced rolling resistance and quicker acceleration.
• Low-profile center knobs for fast straight-line performance.
• Raised shoulder knobs for controlled transitions and confident cornering.

Can I use the Dubnital tubeless for race and long rides?

Yes—its Race casing keeps weight down and improves ride compliance for extended efforts, while tubeless compatibility lets you run lower pressures for traction without pinch-flat risk. The tire’s construction also focuses on durability to withstand repeated climbs and sustained high-speed sections.

• Race casing: light and supple for efficient pedaling and comfort.
• Tubeless-ready design gives puncture protection and the ability to use sealant.
• E25 rating increases structural life under e-bike drivetrain loads.

How does the Dubnital handle damp or medium-loose surfaces?

In damp or moderately loose soil the tire keeps predictable steering and a stable footprint, helping you carry speed without sliding unexpectedly. The center tread maintains forward traction while the side knobs engage progressively to preserve control through corners.

• Balanced knob geometry for traction on variable trail conditions.
• Compound tuned to bite in damp patches without excessive drag.
• Optimized spacing to clear mud and reduce clogging.

Is the Dubnital suitable for e-bikes and aggressive riding?

The E25 rating indicates reinforced construction to cope with higher loads and additional wear from e-bike use. This makes the Dubnital a sensible choice for riders who want race-oriented handling but also need extra structural reliability for pedal-assist bikes.

• E25 e-bike rating: stronger sidewalls and carcass for higher stresses.
• Puncture-resistant casing features to reduce downtime on rough routes.
• Designed to sustain speed and acceleration under heavier forces.

Who is this tire for? The Continental Dubnital 29x2.40 is aimed at riders who prioritize speed and precise handling on hardpack, rocky and mixed dry-to-damp trails—cross-country racers, down-country enthusiasts and e-bike riders seeking race-style performance with added durability. If you want a lightweight, tubeless-ready tire that accelerates easily, holds a clean line through corners, and resists typical trail wear, the Dubnital offers a practical blend of fast rolling and dependable grip without unnecessary weight.
