Marin Alcatraz 1 2026
The 2026 Marin Alcatraz 1 is engineered as a purpose-built dirt jump and freestyle mountain bike designed for riders who want a bike that’s ready to perform from the very first drop. Its Series 3 6061 aluminium frame is shaped to withstand hard landings and big air while delivering confident acceleration and control.

Featuring optimised geometry with short chainstays and 135×10 mm horizontal dropouts, the Alcatraz 1 provides predictable handling, easy manuals and a fun, responsive feel on trails, parks and pump tracks. A suspension-corrected Cro-Mo fork and ambidextrous brake routing allow setup flexibility, and reliable mechanical disc brakes ensure consistent stopping power when you need it most. With a clean, straightforward single-speed drivetrain and robust componentry throughout, this bike focuses on what matters: sessioning jumps, perfecting tricks and pushing your limits with confidence.
