Details

Marlin 7 is your best friend on the trail and wherever else you roll thanks to its confidence-boosting trail geometry. It finds the perfect balance between price and performance with an upgraded RockShox suspension fork that makes quick work of rocks and bumps in your path, and the huge gearing range of a SRAM 12-speed SX Eagle drivetrain.

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 and upgraded components that can keep up with your progress.

The tech you get
A lightweight aluminum frame with modern trail riding geometry and internal routing that keeps cables protected and the bike looking sleek. An upgraded RockShox suspension fork smooths out rowdy trails, 12-speed SRAM SX Eagle shifting, and the serious stopping power of hydraulic disc brakes.

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

Why you'll love it

- Marlin Gen 3 gives you serious trail capability, with big tire clearance and slack, confidence-boosting geometry that keeps you stable from singletrack to city

- Its upgraded RockShox fork gives you 100mm of suspension for turning rocks and roots in the trail into smooth-sailing

- Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter

- Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending

- 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

- Sizes X-Small – Small: 27.5-inch
- Sizes Medium – X-Large: 29-inch
