FROM THE TRAILS TO THE COMMUTE, THE TREK MARLIN 4 CROSS COUNTRY MOUNTAIN BIKE CAN HANDLE ANYTHING.The 2019 Trek Marlin 4 Cross Country Mountain Bike's greatest gift is its versatility. It's a great introductory mountain bike at an incredible price, but is also a rugged commuter capable of hopping curbs on the way to class. The flat mountain-style handlebar and disc brakes keep you in control, on or off the trail, while the rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter. Mechanical disc brakes, knobby tires, and 21 speeds make Marlin 4 a great choice.
