Trek Marlin 7 (Gen 3) Hardtail Mountain Bike 2026

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 tons of gears from the SRAM NX Eagle 12-speed drivetrain.
