A RockShox Judy suspension fork leads the way with 100 mm of coil-sprung travel and preload adjustability. It also includes a TurnKey lockout, so you can firm things up on smoother surfaces to maximise efficiency. The fork helps smooth out rocks, roots and uneven ground, making it easier to stay in control on the trail.

Shifting is taken care of by Shimano’s latest CUES U6000 10-speed drivetrain. Built around LINKGLIDE technology, it’s designed for smooth, durable shifting with long-lasting performance, ideal for riders who want minimal fuss with their gear changes. The wide-range 11–48T cassette means you’re well equipped for steep climbs and flowing descents.

Stopping power comes from Shimano MT200 hydraulic disc brakes, giving consistent and dependable braking whether you're riding dusty singletrack or wet city streets. The Bontrager Kovee wheels are tubeless-ready and built tough, while the wide 2.35" Maxxis Rekon Race tyres offer confident traction without compromising speed.

Additional features like internal dropper post routing, rack and kickstand mounts, and Smart Wheel Sizing across the range make this Marlin truly versatile. Whether you’re tackling weekend trails or commuting midweek, the Marlin 6 is ready for it all.

Occasionally, without notice, manufacturers change product design and/or specifications.
