Marin Alcatraz 2 2026 Dirt Jump Bike

Unleash almost endless possibilities in the Matt Jones matrix with the Alcatraz 2.

A jump-busting Manitou Circus Expert fork smooths landings, while PNW’s Range handlebars and Marin CNC stem are the premium touch you deserve. Its Series 3 Aluminum frame is big-line tough and spin-it light. Dialed with 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.
