Our top rigid MTB fork recommendations are the DCB R110i, R110 and R100. Choose the R110i for Boost with internal brake routing, the R110 for Boost with external routing, or the lighter R100 for a non-Boost front hub. Below them are steel, aluminum and premium carbon comparisons.
Why ride a rigid MTB fork?
A rigid fork makes a simple, low-maintenance build with no suspension service or fork bob. It also gives up suspension travel and bump absorption. Match the fork to your terrain and intended use; a rigid conversion changes how the bike rides on rough ground.
Fit comes before material. Match the front hub’s axle diameter and spacing, headset and crown race, brake mount, rotor limits, tire clearance and fork length. A 29er label alone does not establish compatibility. Ask the frame manufacturer about an appropriate rigid fork axle-to-crown length and offset; compare with the intended suspension setup at sag rather than assuming any rigid fork replaces any travel fork.

Which fork should you buy?
Best Boost value: DCB R110i. Its $195 starting price and internal routing make it our first choice when the fit is right. Prefer external routing? Choose the DCB R110. Using a 15×100mm hub? Choose the DCB R100. Select around your existing wheel and frame, not just the lowest weight.
The Surly steel fork favors mounts and low purchase cost, while the eXotic aluminum fork offers another lower-cost comparison; both checked listings have availability limitations. The ENVE offers useful premium features but costs far more than DCB, so it is not our value pick. DCB, ENVE and other named manufacturers are separate brands; style references on DCB listings do not imply affiliation or identical construction.
Before installation
Confirm intended-use and rider/load limits with the fork manufacturer. Check brake-mount type and maximum rotor size before moving an existing brake across. Use the correct crown race, compression hardware and installation instructions for the steerer material. Have a qualified mechanic cut and install the fork if needed. Inspect after impacts and replace damaged components before riding.
