Trek Marlin 7 Gen 3 - Teal to Nautical Navy Fade

It's right for you if...

You want a go-anywhere trail bike that's got upgrades where it matters most, but won't break the bank. You want to build skills on the trail, and need a bike with confidence-inspiring geometry.

The tech you get

A lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and keeps the bike looking sleek. An upgraded RockShox suspension fork that smooths out rowdy trails, 10-speed fuss-free Shimano Deore shifting and the serious stopping power of hydraulic disc brakes.

The final word

The Marlin 7 is the go-to trail bike for those wanting to build skills on the singletrack and get the best bang for their bucks with upgraded suspension and confidence-inspiring geometry.

Why you'll love it

1. You get real-deal modern mountain bike geometry that keeps handling confident when you're on singletrack, but is versatile enough for use on roads and bike trails too
2. Its upgraded RockShox fork gives you 100 mm of suspension for turning rocks and roots in the trail into smooth-sailing
3. Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
4. Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending
5. Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount

Will my bike have a curved top tube?

Smaller frames (XXS-S) 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. The larger frames (M and up) 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.

Sizing & Tech

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.
