The best front mountain bike shock depends on your wheel size, axle, steerer, brake, and preferred travel. The BUCKLOS 26-inch fork is best for riders seeking 100 mm travel with adjustable stiffness, while the BUCKLOS 27.5-inch air fork offers 120 mm travel and a 15 mm thru-axle. The ZTZ forks suit compatible 26- or 27.5-inch bikes needing a 100 mm, quick-release fork. Check every measurement against your frame and wheel before choosing.

BUCKLOS 26-Inch 100mm Mechanical Fork

This BUCKLOS fork is best for riders with a compatible 26-inch bike who want 100 mm of travel and mechanical adjustments. Its specifications include a 28.6 mm straight threadless steerer, 9 × 100 mm quick-release axle, 36 mm offset, and disc-brake design. A manual crown lockout is included.
The listed ABS adjustment lets riders change suspension softness or stiffness for different riding conditions. The fork weighs about 2,598 g, which is useful to consider when comparing complete-bike weight. Choose this model if its straight steerer and quick-release dimensions match your bike. Avoid it if your wheel uses a thru-axle or your frame requires a tapered steerer.
Exceedhub 26-Inch Fork With Crown Lockout

This Exceedhub model is best for riders who want a mechanical fork with a manual crown lockout and a 9 mm quick-release setup. Listed details include a 28.6 mm straight threadless steerer, 120 mm hub spacing, and aluminum-alloy and magnesium-alloy construction. A star nut is included, according to the product information.
There is an important specification discrepancy: the product title states 120 mm travel, while the feature text states 100 mm travel. Confirm the actual travel with the seller before ordering or compare it with your current fork. It is presented in 26-, 27.5-, and 29-inch options, so select the correct size rather than assuming the options are interchangeable.
ZTZ 26-Inch 100mm Disc-Brake Fork

The ZTZ 26-inch fork is best for a 26-inch bike that needs 100 mm travel, a 9 × 100 mm quick-release axle, and a straight 28.6 mm threadless steerer. The listed design includes a crown lockout and is specified for disc brakes. Its construction is described as high-strength aluminum alloy.
Choose this fork if those measurements match your existing setup and you want a lockout for changing riding conditions. Its stated disc-brake design makes brake compatibility a key check; do not assume it fits a rim-brake bike. Confirm steerer length and the rest of your bike’s mounting dimensions before purchase, since the provided details do not list every installation measurement.
ZTZ 27.5-Inch 100mm Disc-Brake Fork

This ZTZ fork is best for a compatible 27.5-inch bike that uses a 9 × 100 mm quick-release wheel. It has 100 mm of travel, a 28.6 mm straight threadless steerer, a crown lockout, and a disc-brake specification. The manufacturer describes the fork as aluminum alloy, with a design intended to support handling and comfort on longer rides.
It is a better match than the 26-inch version when your bike is designed for 27.5-inch wheels. However, wheel size alone does not establish fit: check the axle, steerer, brake mount, and frame requirements. Avoid this model if your bike requires a thru-axle or a tapered steerer.
BUCKLOS 27.5-Inch 120mm Air Fork

This BUCKLOS fork is best for riders with a compatible 27.5-inch bike who want an air spring, 120 mm travel, and a 15 × 100 mm thru-axle. The listing also describes an ABS manual lock switch with six levels of control and rebound damping to manage rebound speed. Its listed weight is about 1,808 g.
Choose it if your front wheel and frame are designed for a 15 mm thru-axle and the fork’s steerer option fits your bike. The listing offers straight and tapered steerer versions, so select carefully; the listed steerer length is 250 mm. Avoid it if your wheel uses a 9 mm quick-release axle, unless the product’s configuration specifically supports your setup.
Buying Guide: How to Choose a Front Mountain Bike Fork
Which measurements should you check first?
Start with wheel diameter, axle type and width, steerer shape and diameter, and brake type. A 9 mm quick-release fork is not the same as a 15 mm thru-axle fork. Likewise, straight and tapered steerers require different frame compatibility. Confirm the fork’s steerer length and brake mounting details against your bike before ordering.
How much travel is appropriate?
Travel is the distance the fork can compress. The options here range from 100 mm to 120 mm, but more travel is not automatically a better match. Use the travel your bike frame and intended setup support. The Exceedhub 26-inch listing has conflicting travel information, so verify that figure before buying.
Should you choose an air or mechanical fork?
The BUCKLOS 27.5-inch fork is the listed air-spring option, with rebound damping and manual control features. The other selected forks are described as mechanical. Compare the adjustment features you need, and check whether the fork’s axle and steerer match your bike; suspension type cannot compensate for an incompatible fit.
What does a lockout do?
A lockout lets a rider restrict fork movement in conditions where less suspension movement is preferred. The selected products specify manual crown lockouts or manual lock switches. Review the exact control and adjustment description for the model you choose, because listed functions differ.
Frequently Asked Questions
Can I install a 27.5-inch fork on a 26-inch bike?
Do not assume it will fit. Match the fork to the wheel size and frame design specified for your bike, and confirm axle, steerer, brake, and clearance requirements.
Is a 9 mm quick-release axle compatible with a 15 mm thru-axle wheel?
No. These are different axle systems. Choose a fork that matches the front wheel and hub, or verify an approved conversion solution for your specific components.
Does every fork listed here work with rim brakes?
No. The ZTZ listings specify disc brakes, and the BUCKLOS 26-inch listing also specifies disc brakes. Check brake type and mounting details before buying.
How can I confirm the steerer fits my bike?
Check whether your frame requires a straight or tapered steerer, its diameter, and the required steerer length. Compare those measurements with the fork and your headset setup.
