ZTZ 180mm Travel Air Suspension Fork
This ZTZ front suspension fork is designed for XC and all-mountain use, delivering 180mm of smooth travel to absorb big drops and rough sections. The reinforced dual-arch design enhances stiffness for precise steering under load. Built from forged 7000-series aluminum, it balances strength with reasonable weight for demanding gravel routes. The 1-1/8″ straight steerer and external rebound damping options simplify tuning for a wide range of frames and rider weights. An oil/gas hybrid system maintains consistent performance on long descents, and crown lockout supports efficient climbing when terrain improves.
Compatibility centers on the standard 1-1/8″ steerer and 9mm QR front hub spacing, with 74mm disc brake mounting and 160mm rotor clearance. The fork is designed to handle disc brakes and typical gravel wheel setups, making it a versatile option for riders who encounter frequent tech sections or steep grades. Weight is listed around 2.4 kg, providing a sturdy front end without excessive fatigue on long rides. Overall, it targets riders seeking substantial travel with reliable braking and tunable airflow.
BOLANY 20/24-Inch Suspension Air Fork
The BOLANY 20/24-inch suspension fork is designed for a broad range of 20″ to 24″ wheels, including kids’ bikes, folding bikes, and BMX-style builds that ride off-road. It features a 32mm stanchion with a blend of aluminum and magnesium alloys to balance stiffness and weight. The fork supports 100mm or 135mm travel and offers a 28.6mm (1-1/8″) straight steerer with a 220mm threadless tube length.
The model includes an ABS manual valve lock and quick-release 9mm x 100mm, with optional 15mm thru-axle compatibility. It’s designed to accommodate 2.3″ tires or narrower, plus a 74mm disc brake spacing for rotor compatibility. Internal design updates aim to reduce oil leakage and friction, improving overall feel and reliability on rough surfaces. This fork suits riders who want a versatile, budget-friendly suspension option for smaller-wheeled bikes used on gravel paths or mixed-terrain rides.
ZTZ 4.0-Inch Fat Tire Air Suspension Fork
This ZTZ fat-tire fork is purpose-built for 4.0″ tires, offering a stout setup for heavier gravel or light-fat-tire adventures. It supports a 28.6mm (1-1/8″) steerer with a 220mm threadless crown tube and a 9mm QR through-axle configuration (135mm). The 130mm travel is tuned to dampen large hits while preserving steering clarity on technical sections. The inner tube diameter and overall geometry emphasize a balance between stability and compliance on rough roads.
The fork uses an air-spring system with external damping control and is designed for compatibility with disc brakes, including rotor sizing around 160mm. Weight is kept reasonable for a fat-tire setup, enabling confident handling without excessive unsprung mass. This option targets riders exploring wide-tire gravel routes who want substantial front-end travel without jumping to a full-fat bike.
BSFHQS Gravel Rigid Fork (Carbon, 700C)
This rigid fork from BSFHQS is a carbon fiber option designed for gravel and cyclocross use on 700C wheels. It features a straight 1-1/8″ tube with a bottom file specification and a 28.6mm diameter. The fork supports a 12x100mm thru-axle and is compatible with disc brakes (74mm rotor spacing). The carbon blades are positioned to reduce road vibration more effectively than steel or aluminum, contributing to a smoother ride over rough gravel roads. With a length around 300mm and a 50mm offset, the design emphasizes stiffness and precise steering in mixed-terrain riding.
As a rigid fork, it removes suspension complexity and maintenance while delivering predictable steering and strong brake performance. It suits riders who prefer a minimal, rigid front end for speed-oriented gravel riding, gravel-turned cyclocross, or everyday pavement-to-dirt transitions where light weight and low maintenance are priorities.
BUCKLOS Gravel Carbon Fork (700C)
The BUCKLOS carbon fork for 700C wheels uses a 3K carbon fiber construction designed to maximize stiffness-to-weight ratio. It emphasizes a lightweight profile with improved vibration damping compared with metal forks. The fork is designed for disc-brake setups and features a 1-1/8″ tapered tube with a 40mm offset for stable steering geometry on gravel courses. The 12x100mm thru-axle option further improves rigidity and brake alignment, making it a strong choice for riders who prioritize minimal flex and edge control on rough gravel.
Engineered for gravel applications, this rigid carbon fork aims to reduce overall bike weight while maintaining durability and brake compatibility. Its carbon construction helps dampen smaller road vibration and improves comfort over longer rides without the added maintenance of suspension components. This option suits riders seeking a straightforward, high-stiffness front end with confident handling in varied terrain.
Buying Guide
Key factors to consider
- Travel and ramp: Choose suspension with travel that matches terrain. Heavy-descent gravel or mixed terrain benefits from 150–180mm options; smoother gravel may perform well with 100–130mm models.
- Frame compatibility: Verify steerer diameter (1-1/8″ standard or tapered), axle type (QR vs thru-axle), and wheel size support (700C vs smaller wheels). Ensure the fork’s spacing aligns with your frame and brakes.
- Material and weight: Aluminum forks are durable and affordable; carbon forks save weight and improve vibration damping but cost more and can be less forgiving on impacts. Consider your riding weight and terrain when choosing material.
- Tire clearance: Check the maximum tire width the fork can accommodate. Fat tire forks offer more traction but require wider space in the frame and fender/mudguard compatibility.
- Braking compatibility: Ensure rotor size compatibility and that the fork supports your brake type (mechanical/hydraulic disc). 74mm or 76mm disc mounting spacing is common on many gravel forks.
- Maintenance and serviceability: Air-sprung forks require regular air spring service, damper maintenance, and seal checks. Rigid forks depend on fewer parts but demand precise alignment and axle maintenance.
Suspension vs rigid for gravel riding
Suspension forks provide comfort on rough gravel and technical terrain, absorbing big bumps and uneven surfaces. They can add confidence on long descents but require maintenance and can add weight. Rigid forks are simpler, lighter, and lower-maintenance, delivering direct, predictable steering and often better energy transfer on smoother sections. The best choice depends on terrain frequency, rider weight, and willingness to perform regular maintenance.
Practical comparisons
- Best for aggressive descents and rough trails: ZTZ 180mm travel suspension offers substantial front-end damping and tunable air pressure.
- Best for wider tires and mixed-terrain comfort: ZTZ 4.0-Inch Fat Tire suspension supports larger tires and stable handling on uneven paths.
- Best budget suspension option for small-wheel setups: BOLANY 20/24-Inch Suspension Air Fork provides versatile wheel compatibility with reduced cost.
- Best carbon-fiber rigidity for gravel efficiency: BUCKLOS Gravel Carbon Fork delivers low weight and stiff steering with minimal maintenance.
- Best all-around for low-maintenance gravel riding: BSFHQS Gravel Rigid Fork combines carbon damping benefits with a simple rigid design.
Maintenance tips
- Regularly inspect air seals and dampers on suspension forks; replace O-rings and seals as needed to prevent leaks.
- Check torque on through-axles and ensure correct alignment with disc brakes to avoid rotor rub.
- Clean and lubricate stanchions after rides in muddy or salty conditions to extend seal life.
- For carbon forks, avoid over-tightening clamp bolts and follow manufacturer torque specs to prevent stress fractures.
