Trek Marlin 7: a fast cross country hardtail that will hold its own against Trek's higher-end race bikes.

Available in Matte Nautical Navy/Matte Anthracite, Gloss Miami Green or Marigold to Radioactive Red Fade

Trek describes Marlin 7 as "where race-worthy mountain bikes begin". What this means is the precision levels, componentry and handling begin to enter the realm of a performance bike.

A smooth, lightweight RockShox fork leads the way on this fast cross-country hardtail, with a precision component package and tried-and-true, highly refined Trek Alpha Aluminum frame.

It's right for you if...

You're new to the trail, or upgrading from an entry level bike, and have increasing trail aspirations. You want a versatile mountain bike with upgrades on the parts that make a big difference in performance, like a higher quality suspension fork and a simple 1x drivetrain. A bike that's race worthy, should you decide to go fit that.

The tech you get

Internal shift cable and brake hose cable routing, a smoother-feeling RockShox Judy fork with a lockout, Shimano hydraulic disc brakes, and tubeless ready Bontrager wheels.

A simple 1x drivetrain ditches the front derailleur for less clutter and easier operation. Wide-range 11-46 cassette with all the gears you need for clawing up  steep climbs in Marin or Tahoe and blazing down descents.

The final word

A solid fork and frame, wide range of gearing, and quality parts make it the best choice in the Marlin lineup in terms of bike for the money. It’s fully capable of taking on big trail adventures and XC races.

Sizing and Fit

The charts below show Trek's recommended fit across the Marlin line based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts here at Sunshine Bicycle Center.
