It's right for you if...

You're new to the trail but have serious singletrack aspirations, and want a race-worthy mountain bike with upgrades on the parts that make a big difference in performance, like a higher quality suspension fork.

The tech you get

The flagship model of the Marlin lineup has a lightweight Alpha Silver Aluminum frame with internal routing to protect your cables and add to the bike's sleek look, a high-quality RockShox fork with a lockout feature and 100mm of travel, a 2x9 drivetrain, Shimano hydraulic disc brakes, and a low-profile Shimano Shadow rear derailleur that's designed to avoid snagging on trail debris.

The final word

The RockShox suspension, wide range of gearing, and quality parts make it the best choice in the Marlin lineup for new mountain bikers who know they want a serious bike for their money. It’s fully capable of taking on off-road marathon rides and XC races.

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal cable routing, which can help your cables last longer by protecting them from the elements.

Sizing & fit

The charts below show our recommended sizes 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 our 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 at your local Trek retailer.
