Best 29er 150mm Suspension Forks for All-Mountain Bikes

150mm forks are a strong choice for all-mountain bikes that need support on rough descents, steeper terrain and faster trail riding while still being practical for long climbs. The right fork balances damping, stiffness, weight and cost for the way you ride.

RockShox, FOX and Marzocchi offer options from value-focused air forks to premium Ultimate and Factory models. The comparison below breaks down five 29-inch, 150mm forks by price, performance, weight, stiffness and best use.

For premium all-mountain builds, compare the RockShox Lyrik Ultimate E1 with the FOX 36 Factory GRIP X. The Lyrik offers adjustable bottom-out support, while the GRIP X offers a trail-focused damper with a firm mode. The FOX 36 GRIP X2 is the option for riders who want more independent damping controls.

For a simpler setup, the Lyrik Select E1 gives you the LinearXL spring platform with fewer controls. The Marzocchi Bomber Z1 RAIL Air is the value-focused choice when a straightforward setup and lower cost matter most.

Before buying: Select the 29-inch, 150mm version and check your frame’s approved travel and axle-to-crown range, steerer, 15×110mm front hub, offset, brake rotor compatibility and tire clearance. The Bomber page includes both air and coil variants. Match the full model generation: earlier Lyrik and FOX versions can have different specifications.
