The Trek Marlin 6 is the perfect ride for progressing your skills on the trails. Its updated, slacker frame geometry makes it easier to control on descents, the RockShox Judy suspension fork takes the edge off bumpy trails, and a dropper post plus a 10-speed Shimano CUES drivetrain give you real trail capability. Integrated rack and kickstand mounts make it easy to add accessories, so it doubles as a tough everyday bike.
