BUCKLOS 20″ Fat Bike Air Suspension Fork — 180mm Travel
BUCKLOS presents a 20-inch fat bike suspension fork with substantial 180 mm of travel intended for snow, sand, and rugged paths. The fork is designed for 9 mm quick-release hubs and 135 mm spacing, with a straight 1 1/8″ steerer. Weighing roughly 2645 g, this model is marketed as lighter than typical oil-spring forks, aiding acceleration on soft terrain. A crown lockout and lockable damping provide riders control when transitioning from rough sections to smoother trails. Before purchasing, verify crown lockout compatibility, QR sizing, and disc brake fit with your frame.
Key features include a generous 180 mm travel tube for maximum elevation over obstacles and a focus on reducing overall bike weight to improve maneuverability on snow and beaches. The fork aims to balance off-road capability with practical daily use, offering a ride that feels both forgiving and responsive on soft surfaces.
Pros:
– High travel for snow and sand
– Lighter than many oil-spring forks
– Lockout options for terrain transitions
Cons:
– Requires model-specific checks for crown lockout and brake compatibility
– Heavier than some aluminum-only designs
BUCKLOS 20″ Fat Tire Air Suspension Fork (Alternate Model)
This variant mirrors the core BUCKLOS design with similar 180 mm travel and 135 mm hub spacing for 20-inch fat tires. The emphasis remains on maintaining a light frame while delivering confident handling across snowy or beach terrain. The 9 mm QR compatibility and crown lockout are highlighted as features for riders who want quick adjustments on the fly. As with all fat bike forks, confirm the exact model fit with your bike’s crown, axle, and brake setup to avoid fit issues during installation.
Considerations include the weight difference compared with oil-spring forks and the potential need for compatible remote lockout or additional braking hardware, depending on your setup. The fork’s robust construction suits riders who encounter varied conditions across trails and coastlines.

A 235 mm length is noted for the steer tube, catering to riders who want a compact setup on larger wheels. This option is suited for riders using 26″ fat tires who need reliable, adjustable suspension without heavy complexity.
Strengths include flexible lockout choices for different ride conditions and compatibility with standard 135 mm hubs. The main consideration is ensuring the lockout wiring and remote mechanism are compatible with your bike’s cockpit and brake setup. Regular maintenance of the locking system helps maintain long-term performance.

Buying Guide: Key Purchase Considerations
- Travel and Terrain: For deep snow or heavy sand, prioritize forks with longer travel (120–180 mm). Shorter travel suits light trail riding or maintenance in drier conditions.
- Steerer and Mounting: Most fat bike forks use a 1 1/8″ straight steerer and 135 mm hub spacing. Confirm compatibility with your frame’s crown, disc brake mount, and axle type (QR vs. bolt-through).
- Lockout Systems: Lockouts help when transitioning from rough sections to flat sections. Check if the lockout is mechanical or remote and whether it works with your handlebars setup.
- Weight vs. Durability: Lighter forks improve acceleration but may sacrifice stiffness. Aluminum and magnesium alloys offer a balance, while steel or dense alloys add durability and strength for aggressive riding.
- Maintenance and Seals: Look for air-spring or oil-spring configurations with accessible service intervals. Regular checkups keep rebound and compression smooth on soft terrain.
- Braking Compatibility: Ensure the fork’s disc brake mounting pattern matches your rotor size and caliper. Some forks specify 74 mm center-to-center mounting.
- Model Fit: Fat bikes vary by tire width (typically 4.0″). Confirm the fork is specified for 4.0″ tires and the tire clearance at full steering lock.
- Warranty and Support: Consider vendor support, replacement parts availability, and warranty terms to minimize downtime after installation.
These forks provide a range of choices for riders targeting snow, beach, and mixed-terrain adventures. When selecting a model, verify compatibility with your bike’s wheel size, brake system, and frame geometry. A properly matched fork will improve ride control, reduce fatigue, and expand your fat bike’s capability across varied surfaces.
