The Trek Marlin 7 Has The Heart Of A Race Bike

This cheap mountain bike is the perfect gateway drug to your next (trail riding) addiction.

  • Wide range of gears with 2x9 drivetrain

  • Wheels and tires aren’t tubeless-ready

Trek Marlin 6 review - MBR

Alan Muldoon

The first of two 29er to make it into the sub 500 category, the Trek Marlin 6 certainly didn't behave like a fish out of water.

  • Top-rate frame quality, available in seven sizes Independent Shimano shifters

  • Cable and chain rattle. Rear tyre is too skinny
