The Alcatraz is crafted to be the ultimate dirt jump and slopestyle bike you'll ever own. Marin collaborated closely with Matt Jones to meet the exact requirements of a modern dirt jump frame. The 6061 Series 3 aluminum frame is built tough to withstand hard knocks. It's rigid for super - fast acceleration and strong enough for heavy impacts. Short stays make manuals a breeze, and the ambidextrous cable routing allows you to set up your brake on either side of the bars. This main Alcatraz frame kit comes with an FSA headset, a Marin chain tension device, and a Marin seat clamp. It's available in two frame sizes: regular and long.

Using your Alcatraz frame kit is easy. First, assemble the frame with the included FSA headset, Marin chain tension device, and seat clamp. You can choose to set up your brake on the left or right side of the bars according to your preference. When riding, the short stays will help you perform manuals more easily. As for maintenance, keep the frame clean after each ride to prevent dirt build - up. Check the chain tension regularly and adjust it using the Marin chain tension device if needed. Also, make sure the headset is properly tightened. Be careful when riding on rough terrains to avoid heavy impacts that could damage the frame. With proper care, your Alcatraz frame will serve you well for a long time.
