Trek Marlin 7 Gen 3, MD, Galactic Grey

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 precise Shimano Deore shifting.

Why you'll love it

1. You get real-deal modern mountain bike geometry that keeps handling confident when you're on singletrack, but it's versatile enough for use on roads and bike paths, too
2. Its upgraded RockShox fork gives you 100mm of suspension for turning rocks and roots in the trail into smooth-sailing
3. Rack and fender mounts make it easy to accessorize, 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 you 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
