Trek Marlin 7 Mountain Bike

The Marlin 7 is top of Trek's Marlin mountain bike family, equipped with technology that makes those little differences noticeably big when it comes to performance. With the Marlin range created to be ideal for weekend trail adventures or off-road commute's to work, the Marlin 7 takes a step up as it's fully equipped to tackle a long day of trails or even cross-country events. Featuring Trek's Alpha Silver Aluminium frame, you're provided with a lightweight base that's also reliable and durable. To ensure you've got a mountain bike that look's smart, Trek used internal cable routing which also helps protect the cables from the elements. To take your riding up a notch, the Marlin 7 is fitted with a high-quality RockShox fork that allows for 100mm of travel as well as incorporating the ability to lock out the suspension altogether. The Marlin 7 is also equipped with a 2x9 drivetrain, giving you a wide range of choice when it comes to gearing so that you've always got 'just the right gear' at hand. With Shimano hydraulic disc brakes also featured, you're able to stay well in control at all times on the Marlin 7 as these provide efficient and reliable stopping power in all weather conditions. The rear derailleur is a low-profile Shimano Shadow that has been designed to prevent any snagging against trail debris from occurring. Just like all Trek bikes, the Marlin 7 frame has a lifetime warranty. It also has the ability to take a rear rack mount which is ideal for commuting or even a trail adventure trip. Finally, the Marlin 7 is available in 7 different frame sizes which each feature Trek's smart wheel sizing to ensure you find the right fit for you, tailored to your geometry for a faster and more efficient ride.
