Choosing a bicycle suspension cockpit fork is less about picking the lowest number and more about matching the stated wheel, steerer, axle, and brake format to the build you have in mind. This group spans a new 27.5-inch QR fork, two new 29-inch choices with notably different configurations, and a used Manitou that is explicitly described as needing service. The listed-price range runs from $59.99 to $181.99, a $122 spread.
Quick take
- Lowest listed-price new fork: the SR Suntour XCE28 is the entry point in this comparison.
- New 29-inch choices: the SR Suntour XCM and Suntour Raidon 34 serve different steering and front-axle configurations.
- Most adjustment-focused specification: the Raidon 34 combines an air spring with lockout and rebound settings.
- Used repair-oriented route: the Manitou Mars 1 has oil leakage and a stated need for seals/service.
Listed-price comparison
| Fork | Listed price | Price position | Configuration cue |
|---|---|---|---|
| SR Suntour XCE28 27.5-inch QR | USD 59.99 | New, 27.5-inch/650B, QR | |
| SR Suntour XCM 29-inch | USD 129.99 | New, 29-inch, 1-1/8-inch steerer | |
| Suntour Raidon 34 Boost 29-inch | USD 181.99 | New, 29-inch, Boost and tapered | |
| Manitou Mars 1 | USD 69.99 | Used, 100mm designation, service needed |
The XCE28 and Mars 1 sit near the low end of the range, but condition separates them: the XCE28 is new, while the Mars 1 is a used fork with maintenance work called out. The XCM occupies the middle price point, and the Raidon 34 carries the highest listed price alongside the most detailed trail-oriented specification.
Decision matrix
Start with the hard-fit decisions before comparing price. Wheel diameter is the first split, followed by the steerer profile and front-axle format. Next, consider whether the braking format and suspension design match the direction of the build. Finally, decide whether a new fork is the priority or whether a used fork needing seals and service fits the project.
For a straightforward selection, the XCE28 is the new 27.5-inch QR option. The XCM is the new 29-inch choice with a straight 1-1/8-inch steerer. The Raidon 34 is the new 29-inch option for a Boost, tapered-steerer setup, while the Mars 1 is the used alternative for someone prepared to address its stated oil leak.
Fork notes
SR Suntour XCE28 27.5-inch QR

The new SR Suntour XCE28 is the clear choice when the target format is 27.5-inch or 650B with a QR front end and a 1-1/8-inch steerer. Its description also specifies a coil spring, 28mm stanchions, aluminum construction, and a 180mm steerer tube. At USD 59.99, it establishes the lowest listed price in the group. The concrete reason to choose it is its complete stated 27.5-inch QR configuration in new condition. Its limitation is equally specific: that wheel-size, axle, and straight-steerer format makes it a focused replacement option rather than the 29-inch Boost/tapered arrangement represented by the Raidon 34.
SR Suntour XCM 29-inch Mountain Bike Suspension Fork

The SR Suntour XCM is a new 29-inch mountain-bike suspension fork with a 1-1/8-inch steerer, making its stated format the main reason to select it. The description identifies it as a new pull from a bike that was never used, and the attributes list aluminum and steel construction. USD 129.99 places it between the XCE28 and Raidon 34 in the price comparison. A useful detail for a build with a defined head-tube setup is the listed 6 5/8-inch tube length. Its limitation is its dedicated 29-inch, straight-steerer specification; it does not occupy the Boost, 1.5-inch tapered category named in the Raidon 34 title.
Suntour Raidon 34 Boost MTB Suspension Fork

Choose the Suntour Raidon 34 when the build calls for the stated 29-inch, 15mm x 110mm Boost, 1.5-inch tapered configuration. It has a 34mm chassis, an air spring, post-mount 180mm disc brake compatibility, adjustable lockout, and multiple rebound settings. The product title also identifies a remote. Its USD 181.99 listed price is the highest of these four forks, and it is USD 52 more than the XCM. The strongest reason to select the Raidon is the combination of Boost axle, tapered steerer, and adjustable air-spring specification. The limitation is that this particular configuration is more specialized than the straight-steerer or QR formats elsewhere in the comparison.
Manitou Mars 1 Mountain Bike Suspension Fork

The Manitou Mars 1 is the choice for a used-fork project where service work is already part of the plan. It carries a USD 69.99 listed price, a 100mm designation, a straight 1-1/8-inch steerer described as 7.25 inches long, and compatibility with V-brakes and disc brakes. The concrete appeal is its lower-price entry into a fork with both brake-format options stated. Its limitation needs to drive the decision: the description says it is leaking oil, its service history is unknown, and seals/service are in order. That makes the Mars 1 a repair-aware option rather than a direct new-fork alternative.
Final recommendation by use case
Pick the SR Suntour XCE28 for a new 27.5-inch QR fork at the lowest listed price. Choose the SR Suntour XCM when a new 29-inch fork with a straight 1-1/8-inch steerer is the defining requirement. The Suntour Raidon 34 is the fit-specific pick for Boost, tapered, air-spring, remote-equipped trail hardware. Select the Manitou Mars 1 only when a used fork needing oil-leak and seal service suits the project.
