Marlin 7 is where race-worthy mountain bikes begin. The smooth, lightweight RockShox fork and upgraded parts make this model the best choice for new riders who want a fast cross country hardtail that will hold its own against our higher-end race bikes.
  • This is one of our most popular bikes for good reason. You get all the value, plus all the versatility—its a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too
  • Its really fun to ride, and feels like a much more expensive mountain bike
  • Great suspension at an even better price
  • The 1x drivetrain gives you all the gears you need and none you don’t
  • Marlin models in XS through S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount

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.

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.

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.
