DNM USD – 6 FAT/SALE

DNM USD-6 FAT Inverted Suspension Fork – 26 Inch, 120mm Travel

The DNM USD-6 FAT is an inverted front suspension fork designed for compatible fat-bike and off-road cycling applications. Featuring a 26-inch wheel specification, 120mm of suspension travel and a single-spring configuration, it offers an adjustable suspension option for riders considering a replacement fork or custom bicycle build.

The fork combines 35mm AL-7075 stanchions with AL-6061 crown and leg components. It weighs approximately 2.5kg and is listed for desert and snow-ground riding, where correct suspension operation and front-wheel compatibility are important.

Key Features

• Inverted fork construction: Upside-down suspension layout for compatible front-end installations.
• 120mm suspension travel: Provides a specified amount of front fork movement.
• 26-inch wheel specification: Listed for 26-inch wheel applications, subject to tyre and frame clearance.
• 35mm AL-7075 stanchions: Identified stanchion diameter and aluminium alloy.
• AL-6061 crown and legs: Published material specifications for these components.
• Rebound, lockout and high-pressure adjustments: Allows configuration of supported suspension settings.
• 15mm axle and 150mm specification: Important measurements for checking front wheel and hub compatibility.
• IS disc brake mount: Designed for compatible disc braking systems.

Inverted Fork Design and Suspension Performance

The USD-6 FAT uses an inverted, or upside-down, fork layout. This design places the suspension components in an arrangement that differs from a conventional upright fork.

The supplier specifies a single-spring design and a three-system damping description. However, it does not explain the internal damping architecture or identify the exact spring rate.

Actual suspension performance depends on rider weight, terrain, spring setup, damping adjustment and the overall geometry of the bicycle or vehicle.

120mm Front Suspension Travel

The fork provides a stated 120mm of travel. This measurement describes the available movement of the fork suspension and is relevant when checking replacement compatibility.

Correct fork travel helps preserve the intended front suspension geometry and clearance of a compatible frame. A replacement with unsuitable dimensions or travel may change steering geometry and handling.

Before fitting, confirm the original fork dimensions, suspension travel and frame manufacturer’s requirements.

Rebound, Lockout and High-Pressure Adjustment

The DNM USD-6 FAT offers rebound adjustment, a lockout function and high-pressure adjustment according to the supplier.

Rebound damping controls how quickly the fork extends after compression. A suitable setting can help the suspension recover between surface irregularities.

The lockout function provides an additional suspension setting, while the listed high-pressure adjustment requires the manufacturer’s technical instructions for correct operation.

The source does not specify adjustment ranges, supported pressures or servicing requirements. Do not alter a pressurised suspension system without the manufacturer’s instructions and appropriate equipment.

Aluminium Construction and Fork Dimensions

The fork features 35mm stanchions identified as AL-7075 aluminium alloy. Its crown and leg components are listed as AL-6061 aluminium.

The published fork weight is 2.5kg, approximately 5.5lb. This measurement provides a useful reference when planning a compatible front suspension installation.

The supplier specifies a 1 1/8-inch steerer tube. However, it does not provide the total steerer length, crown-to-axle measurement or every mounting dimension required for installation.

Wheel, Axle and Brake Compatibility

The USD-6 FAT is listed with a 26-inch wheel specification, a 15mm axle and a 150mm dimension associated with the axle arrangement.

These measurements should be checked against the existing hub, wheel and fork mounting requirements. The source does not separately confirm axle inclusion or detailed hub compatibility.

The fork also features an IS disc brake mount. Brake compatibility depends on the brake calliper, mounting hardware, rotor size and applicable adapter requirements.

Do not assume compatibility with specific Talaria, E Ride Pro, Sur-Ron or other electric dirt bike models without technical confirmation.

Desert and Snow-Ground Applications

The supplier identifies desert and snow-ground riding as intended applications for this fork. These conditions can place additional demands on front wheel clearance, suspension movement and component maintenance.

Correct tyre width, frame clearance and front wheel dimensions must be checked before installation, particularly when using wide tyres.

The source does not provide a maximum tyre width, certified load rating or vehicle weight limit.

Why Choose the DNM USD-6 FAT?

The DNM USD-6 FAT offers a documented combination of inverted suspension construction, 120mm travel, aluminium components, adjustable suspension settings and compatibility-related axle and brake mount specifications.

For riders and builders working with suitable 26-inch fat-bike suspension systems, these features make it a fork worth evaluating when planning a replacement or custom installation.

For customers in Germany, confirm the frame, wheel, axle, steering and brake requirements before purchase. Any applicable road-use approval requirements should also be checked.
