Marin
Pine Mountain2
The Marin Pine Mountain is a dedicated steel hardtail designed for trail riding, bikepacking, and mixed-surface exploration. Updated for 2023, this generation retains the model's core identity—a robust chromoly frame, 120mm of front suspension, and clearance for high-volume 29-inch tires—while pushing the platform toward modern trail standards. Marin lengthened the reach and slackened the front end, creating a chassis that balances loaded touring stability with everyday trail capability.
Positioned as an accessible entry point into steel mountain bikes, the Pine Mountain appeals to riders seeking a durable, versatile alternative to rigid aluminum frames. It serves equally well as a comfortable commuter, a rugged bikepacking rig, or a reliable secondary trail bike. With extensive mounting points across the frame, it is built to carry gear deep into the backcountry without sacrificing the engaging ride quality inherent to steel hardtails.

Geometry & fit.
4 sizes published.
The current Pine Mountain geometry reflects a measured step toward modern trail standards without abandoning its touring utility. Marin slackened the head tube angle to 66 degrees and steepened the effective seat tube angle to 75 degrees. Combined with a longer reach—measuring 450mm on a size medium—this setup centers the rider more effectively between the wheels. The result is a balanced posture that improves stability on steep descents while maintaining an efficient, upright pedaling position for long days in the saddle.
A 44mm fork offset and short 35mm stem keep the steering response predictable, ensuring the bike remains manageable at low speeds when loaded with bikepacking gear. The cockpit features Marin’s Bedroll Bar, which utilizes a distinct 50mm rise, 10-degree backsweep, and a crossbar designed for mounting handlebar bags. While this specific sweep profile caters heavily to touring setups, some riders may find the hand position unconventional for aggressive trail riding. Additionally, the stock 170mm or 175mm crank arms can lead to occasional pedal strikes on technical climbs, a minor tradeoff for the bike's low, stable bottom bracket.

The lineup.
2 builds, ranging $1,499 – $2,399.
The Pine Mountain lineup consists of two distinct builds, separated primarily by frame construction and component tier. The entry-level Pine Mountain 1 utilizes a Series 2 chromoly frame with a 141x9mm quick-release rear dropout. It is equipped with a 120mm RockShox Recon RL fork, a reliable Shimano Deore 11-speed drivetrain, and Tektro four-piston brakes. This model ships with a rigid seatpost, keeping the initial price low while leaving room in the budget for future upgrades.
Stepping up to the Pine Mountain 2 introduces a more advanced Series 3 chromoly frame, which upgrades to a modern 148x12mm thru-axle for increased rear-end stiffness and broader wheel compatibility. The suspension is handled by a stouter RockShox 35 Gold RL fork. The drivetrain moves to a Shimano SLX 12-speed system, paired with TRP Slate EVO four-piston brakes for enhanced stopping power. Crucially, the Pine Mountain 2 includes a TranzX dropper post straight from the factory. Both models roll on 32mm internal width rims wrapped in 29x2.6-inch Vee Tire Flow Snap tires, ensuring high-volume traction regardless of the chosen build level.
From the press.
1 review from the cycling press.
Reviewers consistently praise the Marin Pine Mountain for delivering the signature ride quality of steel at an unusually accessible price point. On the trail, the frame effectively mutes chatter and smooths out rough sections. One tester noted that the chassis "does seem to have a lot of compliance" (YouTube), providing a forgiving ride that prevents the rider from feeling overly fatigued on long or rocky descents. This comfort extends to technical ascents, where the bike's traction and geometry help it excel. A reviewer found that on steep, rocky climbs, the bike "surprised me on just about all of it" and seemed to "eat them up" (YouTube).
While the bike handles general trail duties admirably, testers acknowledge its limitations when pushed to high speeds. The stock tires roll efficiently, but aggressive riders may find they lack ultimate cornering bite, with one reviewer admitting they "don't quite trust these flow snaps" (YouTube) when descending rapidly. Additionally, the bike's overall weight is noticeable, making it less suited for riders focused purely on climbing speed or cross-country efficiency.
Despite minor component critiques—such as low rear hub engagement and an unconventional handlebar sweep—the overall package is well-received. The budget-oriented suspension performs reliably, and the drivetrain shifts cleanly under load. Ultimately, testers view the Pine Mountain as a capable, versatile machine that offers a comfortable alternative to harsh aluminum hardtails without requiring a premium investment.
