Trek Marlin 8 Mountain Bike 2022
The Trek Marlin 8 Mountain Bike delivers hardtail XC performance at great value. This race-ready bike brings together a strong aluminium frame, light Rockshox fork and reliable components, and is designed with size-specific geometry and features to ensure every rider benefits from the same feel and handling. The RockShox Judy Silver fork incorporates a Solo Air spring that makes it easy to fine-tune for different rider weights, and TurnKey lockout means you can roll faster when the trails are smooth or you hit sections of tarmac.
The SRAM SX Eagle 1x12-speed drivetrain offers a wide range of gears, getting you up the steepest hills, and shifting is smooth and precise. Shimano hydraulic disc brakes take care of stopping and work well in all conditions - dry, wet or muddy. Cables are routed internally for a clean aesthetic and reduced risk of contamination, making for easier maintenance. The tubeless-ready Bontrager Kovee wheels are frame size-specific, ranging from 26" to 29", for better control across the board, with the two smallest sizes also having a curved top tube and lower standover height.
