Enter the Matt Jones matrix on the Alcatraz 24" – scaled perfectly for smaller shredders.
The Alcatraz 24" is decked out with no-nonsense ready-to-ride and ready-to-progress parts, including a Tektro hydraulic rear disc brake to boost control. Its Series 3 aluminium frame is big-line tough and spin-it light. Dialed with short chainstays for poppy manuals and a low, short frame, its geometry lets you level up without limits.
Pump lips to get the ultimate boost with the Alcatraz 24"'s suspension-corrected CrMo rigid fork and fast-rolling Vee Tire rubber. Whether you're finding the rhythm at your local six-pack, flowing at the pump track or sessioning your favourite park, the Alcatraz 24" takes care of business. Built from 6061 aluminium, the Series 3 frame has carefully crafted tubes designed to handle the rough and tumble of airborne antics. Scaled specifically for smaller riders, the frame delivers proven construction in a size that fits. BMX converts will appreciate the 24in wheels, and it is race-ready, fitting directly in the Cruiser Class.
Internal cable routing keeps the bike looking sleek and cuts the rattle. Spend less time wrenching with a 73mm BSA bottom bracket and horizontal dropouts, built with a custom chain tensioning device. ISCG 05 chain guide tabs are retention device ready.
