Marlin Frameset Gen 2

You’re looking for a versatile, wallet-friendly hardtail frame set that you can build up exactly the way you want. You'll fly through singletrack, tackle rugged, all-terrain commutes or both, depending on how you spec it.

A lightweight and sturdy Alpha Silver Aluminium frame, internal routing to protect cables from the elements, mounts for a rear rack and kickstand, and a head set. A rear quick-release skewer makes it easy to take off the rear wheel. Designed with Smart Wheel Sizing: smaller frames fit 27.5˝ wheels and larger frames fit 29˝ wheels.

It's a light and capable frame set at great value. You can spec it as a solid cross country mountain bike without breaking the bank, or build up a rugged commuter that easily handles potholes and rough roads.

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 Trek, it's backed by a lifetime warranty

"Unlike some bikes on the cheap end of the spectrum that cater to the recreational user, this one is aimed firmly at entry-level riders who want a bike that's affordable yet capable of riding and racing hard."

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.

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.

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.

Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.

Going for a long ride? Rack mounts make carrying accessories a breeze.

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
