Choosing a replacement fork for your bike comes down to three big questions: wheel size, steerer type, and brake mount. The fork also has to match how you ride - some riders need suspension travel to smooth out trails, while others just want a rigid fork to keep a commuter or fixed-gear bike rolling. The four forks here span from a $29.99 26-inch suspension fork to a $95 air-sprung disc fork, so you can see what each price tier buys you.
Quick Take
If you're on the tightest budget and have a 26-inch mountain bike, the Ground Assault fork at $29.99 is the least expensive path to suspension. If you want air-sprung adjustability like rebound damping and a lockout, the BUCKLOS fork at $95 is the feature leader, but it's used. For a 700C bike with caliper brakes and a threaded headset, the Threaded 700C fork is the only new rigid option at $39.99. If your build is 27.5-inch with disc brakes, the SR Suntour XCT at $64.99 is the matching choice, though it's used and lacks a lockout.

Product Notes
Ground Assault 26\" White Suspension Fork

At $29.99, this is the least expensive fork here. It's a 26-inch suspension fork in white from Ground Assault, and it's listed in new-other condition rather than as a new retail item. The price makes it a low-risk starting point if you need a basic suspension fork for a 26-inch mountain bike. The main limitation is that it's built for 26-inch wheels, so it won't work on a 27.5-inch or 700C frame. The white finish also stands out, so it may not match a bike with black components.
BUCKLOS 26\" Air Suspension Fork

The BUCKLOS is the highest-priced fork here at $95, and it's also the most adjustable. It uses an air spring with 120mm travel, offers manual lockout and rebound adjustment, and has a disc brake mount. It's built for a 1-1/8\" threadless steerer and 9mm quick-release axle, so it fits a typical mountain bike front end. The compatibility is aimed at Suntour-style forks, which narrows the list of bikes it fits. The main drawback is that it's listed as used, so you're getting pre-owned hardware rather than a new part, and the black finish might not match every frame.
1-Inch Threaded 700C Fork

This is the only rigid fork in the group and the only one sold as new. It's a 1-inch threaded fork for 700C wheels, with a single-shoulder design and hi-tensile steel construction, and it's priced at $39.99. A caliper brake mount is built in, which makes it a natural match for road bikes, cruisers, fixed-gear bikes, and commuters that use rim brakes. The trade-off is that it has no suspension, so it won't soak up trail impacts. It also won't work with disc brakes, and its 700C wheel size means it's not for 26-inch or 27.5-inch builds.
SR Suntour XCT 1-1/8\" Threadless Suspension Fork

This used SR Suntour fork is the only option here sized for 27.5-inch wheels, with a 1-1/8\" threadless steerer and a post-mount disc brake tab, so it suits a mountain bike that runs disc brakes. It has preload adjustment only, with no lockout, so you can set the initial spring tension but can't stiffen the fork for extended climbs. The used condition means it shows some scuffs, though it's still fully functional. If you're building a 27.5-inch disc-brake bike and can accept pre-owned hardware, this fork matches that wheel size at $64.99.
Final Recommendation
Match the fork to your wheel size first, then think about suspension and brake needs. For a 26-inch bike you have two choices: the Ground Assault at $29.99 if you want a simple, low-price suspension fork, or the BUCKLOS at $95 if you want air adjustability, a disc brake mount, and can accept used condition. For a 700C bike with caliper brakes, the 1-Inch Threaded 700C fork is the only new rigid option and costs $39.99. If you're on a 27.5-inch disc-brake bike, the SR Suntour XCT is the matching choice, but keep in mind it's used and lacks a lockout. The right fork is the one that fits your wheel size, your brake standard, and your price range.
