Trek Marlin 7 Gen 3
Details
Marlin 7 is where race-worthy mountain bikes begin. The upgraded parts make this model the best choice for new riders who want a fast cross country hardtail that will hold its own against our higher-end race bikes.
The new Marlin Gen 3 offers confidence inspiring geometry that features a slacker head tube angle which boosts stability and control for confidence when descents get steep and rowdy.
This is one of Trek's most popular bikes for good reason. You get all the value, plus all the versatility—it's a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too.
The Marlin 7 features a smoother-feeling 100mm travel RockShox Judy fork with lockout for pavement or hard surfaces where speed is welcomed. A 1x10 Shimano Deore drivetrain that ditches the front derailleur for less clutter and easier operation. The wide-range cassette still gives you all the gears you need for big climbs and steep descents. Powerful hydraulic disc brakes that work well in any weather.
What you get over Marlin 6:
- The smoother and lighter RockShox Judy coil spring fork with 100mm travel.

Wheel size:
- Sizes Small: 27.5-inch
- Sizes Medium – XX-Large: 29-inch"
Full-length, full-coverage guards on the chainstay protect your frame and keep your ride quiet.
Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter.
A new Thru-Skew axle provides better rear wheel security, holding your wheel in place snugly and ensuring it doesn't slip out of the frame, even when you're rolling through rough-and-tumble terrain.
