Trek Marlin 7 review

Bikes are built for different purposes. In the case of the Trek Marlin, it was built for mountain racing. With its Alpha silver aluminium frame that is decked with a RockShox fork and an 18 speed drivetrain, the bike can meander along mountainous trails at top speeds.

The Shimano MT200 hydraulic brake discs also lend credence to the ability of the bike to stop abruptly with the least effort. The Bontrager XR2 tires also helps in traction as it was threaded for tough situations.

4 Core Features

Alpha Silver Aluminum Frame – The Trek Marlin 7 features an Alpha Silver Aluminum Frame that is light in weight and stress-resistant. Adding to its demeanor is the kickstand mount that accompanies the bike with a chainstay disc brake mount that holds the brake in place.

Bontrager XR2 Comp 29×2.20” Tyres – There is no better confidence in riding a bike on a long-distance journey than having a strong grip on the road. The tires of the Trek Marlin 7 were aggressively designed with high-quality Bontrager covering for optimum traction.

Shimano Altus 2×9 Speed Drivetrain – Equipped with a Shimano Altus 2×9 Speed Drivetrain feature that gives the bike the double of what a regular 9-speed drivetrain bike has to offer without any hiccups when performing a shift at any point.

Equally bedecked with Shimano brakes to support whatever the Shimano Altus drivetrain is thrusting.

RockShox XC 30 coil spring 100mm air fork – This feature is a perfect and the ideal inclusion for bike riders who prefer a comprehensive fork that does extremely well on different grounds. The RockShox suspension fork with a 100mm QR and a turnkey lockout keeps the bike in great shape whilst taking on any terrain
