Marlin 4 is the perfect gateway to trail riding. It's ideal for new riders who want a mountain bike with knobby tyres, that can double as a rugged commuter. Disc brakes, front suspension, 21 speeds and mounts for a rack and mudguards make this a great bike for new trail riders and campus commuters alike.
