Marin Alcatraz 2 Dirt Jump Bike 2026

With Alcatraz 2’s sorted spec, nothing holds you back. Boost higher, dump the front end deeper or push for that flip – Alcatraz gives you the freedom. Big move confidence is backed up by Manitou Circus Expert’s 100mm of travel. PNW’s 38mm rise Range handlebars take the sting out of harsh landings while looking the part. Keep your speed in check with Tektro’s four-piston hydraulic rear disc brake. Our spot-on build keeps maintenance to a minimum without stripping features and lets you push your limits.

Built from 6061 aluminum, the Alcatraz’s Series 3 frame has carefully crafted tubes designed to handle the rough and tumble of your airborne antics.

Lightweight and tough, the frame has got what matters and none of the clutter that doesn’t. Internal cable routing keeps it looking sleek and cuts the rattle. Spend less time wrenching and more time sending with a 73mm BSA bottom bracket and horizontal dropouts, built with our custom chain tensioning device. ISCG 05 chain guide tabs are retention device ready – perfect for the wildest tricks.

Dial up or tone down the party vibes with two frame sizes – long or short. The short frame keeps you connected to your BMX roots, while the long frame offers a calmer ride and fits riders 5ft 11in or taller.
