Core Features


The Trek 7 might be nothing without its core features. After all, its features help this bicycle stand out from the crowd.

Some of its highlighted features are:

1. Drivetrain: The Trek Marlin 7 has a drivetrain of 2×9, which makes the machine both efficient and lightweight. Moreover, this feature comes with a 36/22t crankset connected to an 11-36T cassette.

The figures mentioned above translate to a broad gear range for individuals that might be new to the mountain biking scene. Moreover, its drivetrain helps reduce the overall time to transition between different gears. Thus, thanks to its excellent drivetrain, Trek’s Marlin 7 is fast, durable, and high-performing.

2. Fork: As mentioned in the key specifications section, the Marlin 7’s fork comes with a 100 mm RockShox XC 30, which is an adjustable component that delivers improved performance for cyclists.

Additionally, this fork comes with a preload function to help users easily adjust the ride before using trails. This feature becomes essential when using the Marlin 7 to try out different mountain-biking trails.

Users will also find a turnkey lockout feature in the fork. With the relatively straightforward act of flipping its switch, it allows you to easily lock the bike in place.

3. Suspension: It’s important to note that this bike doesn’t have a rear suspension system. To absorb most of the shocks during rides, the bicycle relies on its hydraulic assisted coil spring. Thus, the rear wheel can’t absorb a significant amount of impact, which might lead to increased rider fatigue. Moreover, it means it doesn’t jolt on impact.

Nonetheless, the lack of a rear suspension system makes the fork relatively easy to reach. Also, it saves the bike from long-term wear and tears.

4. Gears: Getting the basic Trek Marlin 7 model will set its riders with 18 gears. Riders can also see their chosen gears on an easy-to-view gear indicator.

Its entire gear system has components made from Shimano, a relatively popular brand among various mountain biking communities for its high-performance gear systems. Furthermore, you’ll get an above-average level of durability for the different parts in this system, including the front and rear derailleur.

5. Frame: This mountain bike’s Alpha Silver Aluminum frame is both durable and lightweight. These characteristics translate to race-ready features while delivering optimum speed and performance during casual rides.

Its 73-degree seat tube angle plus 69.5-degree head tube angle allows riders to take advantage of maximum handling control in different trails and riding scenarios.

Other Options


As mentioned above, the Marlin 7 is the most expensive mountain bike in the Marlin family of mountain bikes. But it also tends to have the best features in comparison with other models. If you want to purchase less expensive models, you can opt for the Marlin 4, 5, or 6 models. The prices for these mountain bikes are USD$490, USD$550, and USD$650, respectively.

But if you’re looking for other options outside the Trek line, you may consider the brand’s Giant Talon 2. This mountain bicycle boasts a similar price tag with the Marlin 7, but it may have one key difference–the gear system. It’s because the Giant Talon 2 has a slightly-improved gear system than the Marlin 7.

However, the differences might end there since you might call both bicycles as fraternal twins. Both units have 2×9 drivetrains and RockShox fork. Also, both models possess durable aluminum frames and hydraulic disc brakes.

Keep in mind that some performance and quality drops when using these other models. Still, you might consider your budget as you search for your preferred mountain bike.

Buy and use the Trek Marlin 7 to take advantage of its quality specs and features. It even has a relatively inexpensive price tag to fit the spending allowance of various budget ranges.
