It's right for you if...
You’re looking for a versatile, wallet-friendly 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.
The tech you get
A lightweight and sturdy Alpha Silver Aluminium frame, internal shift cable and brake hose routing to protect cables from the elements, mounts for a rear rack and kickstand, and a headset. Designed with Smart Wheel Sizing: smaller frames fit 27.5˝ wheels and larger frames fit 29˝ wheels.
The final word
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
"Look fast, feel fast, go fast."
"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."

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.
Rack mounts

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 retailer.
