Trek Marlin 7 Mountain Bike 2020
Trek's Marlin 7 Mountain Bike is a fantastic entry-level choice for riders looking to get into off-road riding. It pairs a strong aluminium frame with a lightweight RockShox XC 30 fork for 100mm of trail-smoothing travel. This is a bike that'll hold its own against higher-end models with reliable components that includes a 2x9-speed Shimano drivetrain and powerful hydraulic disc brakes. There's plenty of range in the gearing to get you up the steepest climbs and flying down the other side. The Shadow design of the rear derailleur improves performance and reduces chain slap for a quieter ride. Cables have been routed internally for cleaner aesthetics and less chance of contamination, while mounts for rear racks increase versatility, making the bike suited to adventure riding and commuting too. Rolling on wheels sized to match the frame size - 27.5" or 29" - you're guaranteed of the perfect blend of efficiency, speed and control.
Features
- Race-worthy mountain bike that has rear rack mounts if you use it for commuting too
- RockShox XC 30 100mm travel fork
- 2x Shimano drivetrain
- Backed by Trek's lifetime warranty
