Trek Marlin 6 review

Dec 2015 · Guy Kesteven

Violently uncontrolled fork and blunt frame lead a list of reasons that Trek’s Marlin is best kept away from real off roading. Buy if you're a glutton for punishment looking to get into mountain biking

Highs
  • Size-specific wheels, range of paint jobs available

Lows
  • Punishingly stiff frame and handlebars, undamped fork, some poor finishing kit
