The Marin San Quentin 2 Hardtail Mountain Bike - 2026 combines robust aluminium construction, advanced suspension, and precise drivetrain performance for confident control in demanding terrain. Built around a Series 3 6061 aluminium frame with internal cable routing, it delivers strength without unnecessary weight. A standout feature is its X-Fusion Slide Boost RC fork with 140mm travel, offering adjustable compression and rebound for optimal handling across varied conditions. This bike is designed for riders who demand stability, grip, and braking power when tackling technical trails.
Key Features and Benefits
- Series 3 6061 double-butted aluminium frame with internal cable routing: Reduces weight while maintaining structural strength. The double-butting process removes material where not needed, keeping the frame light but rigid. Internal routing protects cables from dirt and damage, resulting in smoother shifting and longer cable life.
- X-Fusion Slide Boost RC fork with 140mm travel, compression, and rebound adjustment: Absorbs impacts from roots, rocks, and drops. Adjustable damping allows fine-tuning to match terrain and rider preference. This ensures better control, reduced fatigue, and more efficient power transfer through technical sections.
- Marin aluminium double-wall rims with 29mm inner width, tubeless compatibility: Wide internal diameter supports larger tyres for increased grip and stability. Double-wall construction improves durability against impacts. Tubeless setup reduces puncture risk and allows lower pressures for better traction.
- Shimano Deore 11-speed drivetrain with 11-51T cassette: Offers a wide gear range for both steep climbs and fast descents. Smooth, precise shifting enhances cadence control and efficiency, ensuring consistent performance in varied terrain.
- Tektro M535 4-piston hydraulic brakes with 180mm rotors: Delivers strong, controlled braking with less lever effort. Large rotors improve heat dissipation, ensuring reliable stopping power during long descents or technical riding.
- TranzX dropper post with 170mm travel and remote lever: Allows quick saddle height adjustment without stopping. Lowering the saddle improves manoeuvrability on descents, while raising it restores efficient pedalling on climbs.
This bike is built for riders who want dependable performance on technical trails. Its frame, suspension, drivetrain, and braking system work together to provide precise control, durability, and adaptability in challenging conditions. The wide rims and aggressive tyres ensure grip in loose terrain, while the dropper post adds versatility across climbs and descents.
