Trek Marlin 7 2026 Mountain Bike

The 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 a RockShox suspension fork that makes quick work of rocks and bumps in your path, and loads of gears from the SRAM NX Eagle 12-speed drivetrain.

A lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and keeps the bike looking sleek. A 100 mm RockShox Judy suspension fork that smooths out rowdy trails, upgraded 12-speed SRAM NX Eagle shifting and the serious stopping power of hydraulic disc brakes.

Key Features

• 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


• You get a RockShox fork with 100 mm of suspension that turns rocks and roots in the trail into smooth-sailing and upgraded 12-speed SRAM Eagle shifting


• Mudguard mounts make it easy to accessorise, 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
