Marin Alpine Trail 1 MX - Brown-Blue - 2025
The Alpine Trail series represents Marin’s most advanced and adjustable enduro bikes, built for aggressive riding and all-out performance. The Series 4 aluminum MultiTrac 2 LT frame features a mixed-wheel setup (29” front / 27.5” rear), 170mm front and 160mm rear travel, and a host of adjustability options, including head tube angle, bottom bracket height, and chainstay length. The Bear Box downtube storage keeps essentials secure, while a 34.9mm seatpost ensures compatibility with modern dropper posts.
The Alpine Trail 1 MX might be the entry-level model in the lineup, but it doesn't compromise on performance. Fox suspension keeps things under control, while Shimano Deore 12-speed components ensure smooth shifting. TRP Slate Evo 4-piston brakes with 203mm rotors deliver powerful, fade-free stopping power.
