Key Features:
- Series 2 6061 aluminium frame with modern trail geometry and low standover height
- SR Suntour XCM fork with 120mm travel and hydraulic lockout
- MicroSHIFT Advent 9-speed drivetrain with wide-range 11–46T cassette

The SR Suntour XCM fork offers a confidence-boosting 120mm of travel up front, ideal for smoothing out roots, rocks and rougher terrain. A hydraulic lockout feature helps boost efficiency when you’re climbing or covering ground on tarmac.
The drivetrain is handled by MicroSHIFT’s Advent 9-speed system, with a clutch-equipped rear mech and a wide 11–46T cassette—offering gearing that’s trail-ready without overcomplicating the setup. Tektro M280 hydraulic disc brakes provide reliable stopping power in all weather, while the 29” wheels help roll smoothly over obstacles and keep momentum up on flowy singletrack.
The Bobcat Trail 3 comes with 2.25” wide MTB tyres, offering plenty of grip on a variety of surfaces. It’s finished with Marin’s in-house components, including a comfy saddle and 780mm riser bars for control.
