10 Models Reviewed in Depth
#1. BUCKLOS 180mm Fork
The BUCKLOS 180mm Fork is a powerhouse for downhill and enduro riders. With 180mm travel and a double crown design, it offers exceptional stability and control on steep descents. The 34mm stanchions provide rigidity, and the rebound adjust with 21 clicks lets you fine-tune the ride.
However, the QR axle is a weak point for such a long-travel fork, and the weight is significant. It’s best for riders who prioritize plushness over weight. Skip it if you need a thru-axle or plan cross-country riding.
Pros
- Long travel
- Double crown
- Plush performance
Cons
- Heavy weight
- QR axle
- Overkill for XC
Specifications
#2. BUCKLOS Air Fork
The BUCKLOS Air Fork is a standout for trail riders seeking adjustability. With 140mm travel and a 34mm stanchion, it offers plush performance and precise steering. The rebound adjust with 20 clicks lets you dial in the feel, while the air spring adapts to your weight (50-120kg) for a personalized ride.
One caveat: the fork is QR only, not thru-axle, which limits stiffness for aggressive riding. It’s ideal for XC and AM enthusiasts who want a lightweight, tunable fork without breaking the bank. Skip it if you need a tapered steerer or plan heavy downhill use.
Pros
- Plush air spring
- 20-click rebound
- Lightweight build
Cons
- QR axle only
- Straight steerer
- Not for DH
Specifications
#3. BUCKLOS Thru-Axle
The BUCKLOS Thru-Axle Fork is a modern choice for riders with newer frames. You’ll benefit from the 15mm thru-axle for increased stiffness and the air spring for tunable performance. The 120mm travel is versatile for trail and XC use, and the ABS lockout adds control.
However, the fork is disc-brake only and may require a specific hub. It’s best for riders with thru-axle compatible bikes. Skip it if you have a QR frame or prefer a coil spring for simplicity.
Pros
- Thru-axle stiffness
- Tunable air
- Lightweight
Cons
- Disc only
- Hub compatibility
- Basic damping
Specifications
#4. ZTZ Dual Air Fork
The ZTZ Dual Air Fork stands out for its dual air chamber design, allowing independent adjustment of positive and negative pressure. You’ll get a 120mm travel that’s plush and responsive, and the lightweight construction (1750g) enhances agility. The manual lockout is a bonus for climbs.
However, the QR axle is a limitation for aggressive riding, and the dual air setup requires more maintenance. It’s best for riders who love fine-tuning their suspension. Skip it if you prefer a simple coil fork or need a thru-axle.
Pros
- Dual air adjust
- Lightweight
- Plush ride
Cons
- QR axle
- Complex setup
- Disc only
Specifications
#5. BUCKLOS 120mm Fork
The BUCKLOS 120mm Fork offers an impressive balance of performance and price. You’ll enjoy the air spring that can be tuned to your weight, and the manual lockout is handy for climbs. The rebound adjust adds further customization, making it a great upgrade for cross-country riders.
However, the tapered steerer may not fit older frames, and the QR axle limits stiffness. It’s best for riders on a budget who want air-suspension benefits without the premium cost. Skip it if you need a thru-axle or plan aggressive trail riding.
Pros
- Tunable air spring
- Manual lockout
- Good value
Cons
- Tapered steerer
- QR axle
- Basic damping
Specifications
#6. BUCKLOS 120mm Air
The BUCKLOS 120mm Air Fork is a great choice for cross-country enthusiasts. You’ll appreciate the air spring that can be tuned to your weight and the tapered steerer for added stiffness. The manual lockout is perfect for climbs, and the rebound adjust helps smooth out rough trails.
However, the QR axle is a limitation for aggressive riding, and the fork may feel flexy under hard braking. It’s best for XC and light trail use. Skip it if you need a thru-axle or plan heavy downhill.
Pros
- Tunable air spring
- Tapered steerer
- Lightweight
Cons
- QR axle
- Basic damping
- Not for DH
Specifications
#7. Exceedhub MTB Fork
The Exceedhub MTB Fork offers a solid mix of features for a reasonable price. You’ll get 120mm travel and a manual lockout for efficiency on varied terrain. The aluminum alloy construction ensures durability, and the included star nut simplifies installation.
However, the fork is disc-brake only and a bit heavy at 2.7kg. It’s best for riders who want a reliable, no-fuss fork for trail riding. Skip it if you need a lighter option or have rim brakes.
Pros
- Durable aluminum
- Manual lockout
- Easy install
Cons
- Heavy weight
- Disc only
- Basic damping
Specifications
#8. ZTZ MTB Fork
The ZTZ MTB Fork delivers solid performance for its price point. You’ll appreciate the 100mm travel and crown lockout for climbing efficiency, while the aluminum alloy build keeps it durable without excessive weight. The preload adjust lets you fine-tune the ride to your preference, making it a versatile choice for trail riding.
However, the fork is disc-brake only, so if you have rim brakes, this isn’t for you. It’s best for budget-conscious riders upgrading a basic mountain bike, but expect a firmer feel than pricier air forks. Skip it if you need a tapered steerer or thru-axle for aggressive riding.
Pros
- Affordable price
- Adjustable preload
- Lightweight aluminum
Cons
- Disc brake only
- Straight steerer only
- Basic damping
Specifications
#9. DONSP1986 Fork
The DONSP1986 Fork is a practical upgrade for commuter bikes. You’ll get 90-100mm travel to smooth out city bumps, and the included headset saves you extra cost. The disc brake compatibility is a plus for stopping power.
However, the fork is heavy and has limited adjustability, making it less suitable for serious off-road. It’s best for casual riders or those converting a bike for daily use. Skip it if you need a lightweight fork or plan technical trails.
Pros
- Headset included
- Disc brake ready
- Simple install
Cons
- Heavy weight
- Limited travel
- Basic damping
Specifications
#10. KANGXYSQ Spring Fork
The KANGXYSQ Spring Fork is a simple, reliable choice for entry-level riders. With 110mm travel and a coil spring, it provides basic shock absorption without complexity. The manual lockout is a nice touch for climbs, and the dual brake compatibility (disc and V) adds versatility.
However, the coil spring is heavier and less tunable than air forks, and the rebound adjust is limited. It’s best for casual trail riding or commuter bikes. Skip it if you need a lightweight fork or plan demanding off-road use.
Pros
- Dual brake support
- Simple design
- Affordable
Cons
- Heavy coil
- Limited adjust
- Basic damping

The Fork Buying Trap: How to Get Real Value Without Overpaying
A mountain bike fork is the single most impactful upgrade you can make to how your bike feels, but it’s also the easiest place to waste money. Between confusing travel numbers, damper jargon, and chassis materials, most riders end up paying for features they’ll never use or buying something too stiff to enjoy. This guide cuts through the noise so you spend smart, not just spend more.
The Numbers That Actually Matter (and the Ones That Don’t)
Travel vs. your riding style
More travel isn’t automatically better. A 120mm fork on a trail bike will feel dead and wallowy, while a 150mm fork on a cross-country rig will ruin your climbing efficiency. Match travel to the bike’s intended purpose, not your ego. If you’re on a modern trail bike, 130–140mm is the sweet spot for most riders.
Damper quality over bling
A basic coil or cheap air spring with a poor damper will feel harsh no matter how much you spend. Look for a fork with a tunable rebound and, ideally, low-speed compression adjustment. You don’t need a full cartridge damper, but you do need something that doesn’t pogo or dive under braking. This is where value forks either shine or fall apart.
Chassis stiffness: don’t overthink it
A 32mm stanchion fork is plenty for most riders under 180 pounds. Going to 34mm or 36mm adds weight and cost without a noticeable stiffness benefit unless you’re aggressive or heavy. If you’re shopping on a budget, a quality 32mm fork will feel better than a cheap 34mm.
Axle and steerer compatibility
Check your hub’s axle standard (15×110 Boost is the norm now) and your head tube’s steerer diameter (tapered 1.5″ to 1-1/8″ is standard). Getting this wrong means a $400 paperweight. Measure twice, buy once.
Sticking to your budget
The best value fork isn’t the cheapest one—it’s the one that gives you the damper and travel you need without paying for carbon crowns or exotic coatings. Set a hard cap and prioritize damper performance over weight savings. A heavier fork with a good damper will always ride better than a light fork with a bad one.
Pitfalls That Burn First-Time Buyers
- Buying used without checking the stanchion condition. Scratches and pitting aren’t cosmetic—they destroy seals and cause stiction. Any fork with visible wear is a money pit, no matter the brand.
- Ignoring the bike’s geometry. A fork that’s too long or too short changes your head angle and bottom bracket height, making the bike handle like a shopping cart. Always check the axle-to-crown measurement against your frame’s spec.
- Assuming more adjustability equals better performance. A fork with 20 clicks of high-speed compression you’ll never touch is just extra weight and complexity. You want a fork that’s set-and-forget, not one that requires a suspension engineer’s manual.
The Bottom Line on Budget Fork Value
If you’re chasing maximum travel without breaking the bank, the 180mm BUCKLOS Double Crown is your gravity-fed wildcard. For trail riders wanting tuneable air performance, the 140mm remote-lockout model is the standout all-rounder. The 120mm air forks—especially the 15mm axle version—deliver the best blend of weight, stiffness, and price for XC/AM duty. The cheap coil units are only worth it for rigid-to-suspension conversions on a strict budget.
