Marin Alcatraz Frame Kit - 2026

Handling hard knocks, big sends and lightning-fast acceleration, the Alcatraz 2 frameset is your dream build’s foundation. Its Series 3 Aluminum frame is big-line tough and spin-it light. Fine-tuned by Matt Jones, it’s got short chainstays for poppy manuals and a low, short frame so it won’t cramp your style – its geometry lets you level up without limits.
