Internal cable routing keeps the bike looking clean while protecting cables from dirt and debris, and integrated rack and kickstand mounts make it easy to transform the bike into a capable commuter or touring machine.
Confident Suspension Performance
An SR Suntour XCT 30 suspension fork smooths out rough trails, rocky paths, and uneven roads with up to 100mm of travel (size dependent). Hydraulic lockout allows you to firm up the fork for improved pedalling efficiency on climbs and paved roads.
Shimano CUES 9-Speed Drivetrain
The Shimano CUES U4000 drivetrain is designed for long-lasting durability and dependable shifting performance. Combined with Shimano's LINKGLIDE 11-46T cassette, it provides a wide gear range for tackling steep climbs, flowing trails, and fast descents with confidence.
Powerful Hydraulic Disc Brakes
Shimano MT200 hydraulic disc brakes deliver smooth, reliable stopping power in all weather conditions, providing excellent control whether you're descending technical trails or navigating busy city streets.
Built for Comfort and Control
Wide Bontrager XT3 2.4" tyres provide outstanding grip, confidence, and stability across loose dirt, gravel, and pavement. Bontrager alloy handlebars, lock-on grips, and size-specific cockpit components ensure a comfortable riding position for every frame size.
Adventure-Ready Versatility
The Marlin 5 Gen 3 is designed to grow with your riding ambitions. Rack and kickstand compatibility make it perfect for commuting and bikepacking, while internal dropper post routing allows easy future upgrades for more technical trail riding.
Ride Anywhere with Confidence
Whether you're discovering mountain bike trails for the first time, riding to work, or heading out for weekend adventures, the Trek Marlin 5 Gen 3 delivers dependable performance, everyday comfort, and outstanding value in one capable package.
