A legendary hardtail made for aggressive riding

The Dartmoor Hornet has earned its reputation as one of the most respected hardtail mountain bikes in the gravity scene. The latest generation features a modern Mullet wheel setup with a 29" front wheel and a 27.5" rear wheel, giving you the confidence to tackle steep descents, technical trails and large features without sacrificing agility.

This is not a bike built for gentle rides around the park. The Hornet is designed for aggressive enduro, bike parks, jumps, rock gardens, root-covered trails and fast technical descents. Its robust aluminium frame, long-travel X-Fusion suspension fork and progressive geometry create a hardtail that feels composed when the trail gets rough.

Why choose the Dartmoor Hornet?

The Hornet is built for riders who demand confidence and control on challenging terrain. Its slack geometry, long front centre and mixed-wheel platform create a stable ride at speed while keeping the bike responsive through tight corners and technical trail sections.

The 150 mm X-Fusion suspension fork absorbs heavy impacts with ease, while powerful Shimano hydraulic brakes help you stay in complete control during steep descents. Whether you enjoy natural mountain trails, bike parks or jump lines, the Hornet is ready for every challenge.

Who is the Dartmoor Hornet for?

The Hornet is an excellent choice for riders who enjoy aggressive trail riding, enduro adventures, bike parks and technical mountain terrain. It is equally at home on rocky descents, root-filled forest trails, drops, jumps and demanding singletrack.

If you are looking for a durable hardtail that lets you push your limits while remaining predictable and confidence inspiring, the Dartmoor Hornet is built for exactly that purpose.

Frame size guide

• Size S: Recommended rider height approximately 160–170 cm
• Size M: Recommended rider height approximately 170–180 cm
• Size L: Recommended rider height approximately 180–190 cm
• Size XL: Recommended rider height approximately 190–200 cm

Choosing the correct frame size has a significant impact on comfort, handling and confidence. A smaller frame feels more playful and easier to manoeuvre, while a larger frame provides additional stability during fast descents and high-speed trail riding.

Why ride a Mullet MTB?

A Mullet bike combines two wheel sizes to maximise performance on modern trails. The larger 29" front wheel rolls over rocks, roots and rough terrain more easily while delivering better grip and stability. The smaller 27.5" rear wheel keeps the bike agile, making it easier to corner, manual and change direction quickly.

This combination has become a favourite among enduro and gravity riders because it offers the stability of a 29er together with the playful handling of a smaller rear wheel.

Modern geometry for demanding trails

The Dartmoor Hornet features progressive geometry designed for aggressive mountain biking. A slack 64° head angle inspires confidence on steep descents, while the long reach gives you plenty of room to move around the bike when the terrain becomes technical.

Short 425 mm chainstays help keep the bike responsive and playful, making manuals, cornering and quick direction changes feel natural without sacrificing stability.

X-Fusion Trace 36 RC suspension fork

The X-Fusion Trace 36 RC fork offers 150 mm of travel and is built to handle demanding terrain. Its 36 mm stanchions provide excellent stiffness for accurate steering and greater confidence during high-speed descents, large drops and rough rock sections.

Combined with a Boost thru axle and the Hornet's progressive frame geometry, the suspension delivers precise handling and dependable control when the trail becomes fast, steep and technical.

Microshift Advent 1x9 drivetrain built for aggressive riding

The Dartmoor Hornet features a Microshift Advent 1x9 drivetrain with a clutch rear derailleur and an 11-42T cassette. This setup provides a wide gear range for technical climbs while keeping the chain secure during rough descents, jumps and rock gardens.

A single chainring drivetrain is simple, reliable and easy to maintain. With fewer components to worry about, you can stay focused on the trail instead of your gears.

Shimano hydraulic brakes for maximum control

Shimano MT410 hydraulic disc brakes with a 203 mm front rotor and a 180 mm rear rotor deliver powerful and consistent braking performance. Whether you are charging down steep descents or approaching technical features, you can control your speed with confidence.

Built to handle demanding terrain

Dartmoor Raptor rims are Tubeless Ready, making it easy to switch to a tubeless setup in the future. Lower tyre pressures improve grip, comfort and puncture resistance on rough terrain.

The wide Vee Tire Crown Gem tyres provide excellent traction on loose dirt, rocks and roots, helping you stay in control even when the trail becomes unpredictable.

Ride protected

Technical mountain biking deserves proper protection. Before hitting the trails, choose a quality MTB helmet and protective gear to help reduce the risk of injury.
