SKU5301834
Marlin 4 is the gateway mountain bike that will take you from rail trails to singletrack. It's ideal for riders who want a mountain bike with knobby tires that can double as a rugged commuter. Disc brakes, front suspension, Shimano 14-speed shifting, and mounts for a rack and fenders make this a great bike for trail riders and campus commuters alike.
OVERVIEW
It's right for you if...
You want an introductory mountain bike at an incredible price, but also want a commuter that's rugged enough to hop curbs on the way to class.
The tech you get
A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, trustworthy 14-speed Shimano shifting with a wide range of gearing so you always have the right gear for your terrain, powerful mechanical disc brakes, and a suspension fork that takes the edge off bumps and rough terrain.
The final word
Marlin is made for any adventure. The rack and fender mounts make it a great choice for commuters who want to get a little rad on the way to class or the grocery store.
