Marlin Frameset is a lightweight, versatile mountain bike frame great for building up as a fast cross country race bike or a rugged flat bar commuter. It's made of strong Alpha Silver Aluminum and is quick and capable on pavement, gravel, and singletrack alike.

• All the value, plus all the versatility—it's a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too
• It's really fun to ride, and feels like a much more expensive mountain bike
• Internal cable routing extends the life of your cables and adds to the bike's sleek look
• Like every model in the Marlin family, it's backed by Trek's lifetime warranty

Will my bike have a curved top tube?

Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

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 shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.
