Trek Marlin 6 review - MBR

Jun 2019 · 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.

Highs

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

Lows

  • Cable and chain rattle. Rear tyre is too skinny
