The Series 3 aluminum frame is built for the hard knocks and is stiff enough for lightning-fast acceleration and tough enough for the heavy hits. Short stays keep manuals easy and ambidextrous cable routing means you can run your brake on the left or right of the bars. There’s a 100mm Manitou Expert coil fork, front and rear Tektro hydraulic disc brakes, Vee Tire rubber and plenty of bombproof Marin components. Best of all, it’s available in two frame sizes, regular and long.
