Marin Kentfield 2 ST - 2026

The Marin Pine Mountain 2 is our high-end, high-performance steel bikepacking mountain bike hardtail. Our Series 3 CrMo version of the frame upgrades to higher-grade CrMo for a lively, zippier ride and has a bolt-through rear axle for a little added stiffness where it matters. It’s built up with a RockShox FS 35 fork, Shimano SLX 12-speed drivetrain, Vee Tire Flow Snap 2.6” tires, powerful Shimano brakes and a super-useful dropper post for added comfort and speed. Last but not least, you’ve got our much-loved Marin Bedroll handlebar.

Key upgrades over the Pine Mountain 1:

• Series 3 CrMo frame w/12x148mm custom cast thru-axle dropouts
• RockShox FS 35 fork
• Shimano SLX 12-speed drivetrain & FSA Grid crankset
• Shimano MT520 brakes
