2025 Marin Alpine Trail XR Mountain Bike

2025 Marin Alpine Trail XR Enduro Mountain Bike

The 2025 Marin Alpine Trail XR is purpose-built for riders who demand high-end enduro performance without overspending. Built around Marin’s refined Series 4 aluminum MultiTrac 2 LT frame, this machine utilizes a mixed 29”/27.5” (Mullet) wheel setup and long-travel suspension to thrive on the world's steepest and most technical terrain.

Xtra Rad (XR) Enduro Performance

True to its "Xtra Rad" designation, the Alpine Trail XR delivers a premium riding experience. Marin has paired the elite RockShox Ultimate-level suspension with a reliable SRAM GX Eagle Lunar 12-speed drivetrain. This combination ensures that whether you are charging through rock gardens or pedaling back to the summit, you have the precision and durability required for aggressive mountain biking.

Adjustable Geometry & Smart Storage

• Fully Customizable Handling: Fine-tune your setup with an adjustable head tube angle, bottom bracket height, and chainstay length to perfectly match your riding style.
• Integrated Bear Box Storage: The downtube features a secure storage compartment with a zippered internal bag, perfect for carrying essential trail tools and spare parts.
• Mixed Wheel Versatility: While optimized for a Mullet setup, the frame provides the flexibility to support a full 29” rear wheel configuration.
• Maximum Control: Equipped with SRAM DB8 4-piston hydraulic brakes and a 200mm front rotor for consistent, powerful stopping performance on demanding descents.

The Alpine Trail XR is the ultimate choice for riders seeking a "gravity-first" bike that doesn't compromise on build quality. Featuring a RockShox Zeb Ultimate fork with 170mm of travel and a Super Deluxe Coil Ultimate rear shock, it provides a plush, bottomless feel that inspires confidence on every run.
