TREK Marlin 7 Gen 3 Hardtail Mountain Bike in Fury Red and Lithium Grey Fade

Season:2026

Brand:Trek

Code:57367RED

The Marlin 7 Gen 3 hits the sweet spot for riders ready to upgrade their off-road game. It combines modern trail geometry with race-worthy components to deliver a hardtail that’s fast, confidence-inspiring, and versatile enough to double as a daily ride. With a RockShox Judy fork, wide-range 12-speed SRAM NX Eagle drivetrain, and hydraulic disc brakes, it’s built to tackle singletrack with precision — all at a price that makes sense.


Key Features

  • Modern trail geometry with longer reach and a slacker head angle for more stability on descents

  • 100mm RockShox Judy Silver fork with lockout for efficient climbing and smooth trail control

  • SRAM NX Eagle 12-speed drivetrain offers a huge gear range with reliable single-shifter simplicity

  • Powerful hydraulic disc brakes for confident stopping in wet or loose terrain

  • Internal cable routing keeps the bike clean-looking and makes it dropper post–ready

  • Thru-Skew rear axle system adds stiffness and strength over standard quick releases

  • Rack, mudguard and kickstand mounts for daily commuting or weekend bikepacking

  • XXS and XS sizes feature a lower standover height and curved top tube for smaller riders


The Bottom Line

The Marlin 7 Gen 3 is perfect for riders who want a real-deal trail bike with smart upgrades where it counts — especially in the drivetrain and suspension — while keeping the price in check. Whether you're hitting singletrack or riding to work, it's the performance-focused hardtail that’s ready for anything.
