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.
The Main Alcatraz frame kit comes supplied with an FSA headset, Marin chain tension device and Marin seat clamp. Available in two frame sizes, regular and long.
