Marlin 5 is a great ride for all your adventures. It's also versatile and a popular ride on college campuses because the rack and kickstand mounts make it easy to accessorize and haul a load.
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
- Fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
- Its ThruSkew system is safer, simpler, and stronger, plus it makes removing the rear wheel easy for flat fixes in a pinch
- 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
A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, an upgraded 9-speed Shimano CUES drivetrain, a wide range of gearing so you always have the right gear for your terrain, powerful hydraulic disc brakes, and a terrain-smoothing suspension fork with a lockout.
It's right for you if...
You're new to the trail and you’re looking for a real mountain bike that doubles as a commuter — and you want it all at an exceptional value.

FEATURES
Will my bike have a curved top tube?
Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
High tech, high value
Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.
Shimano CUES
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette, and chainrings.
Shimano LINKGLIDE
LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
