+3532840609We've taken the Alcatraz 1 and scaled it down for smaller riders. Built upon the same tubing as the larger models, it features a 360mm reach, 69° headtube angle, and 72° seattube angle, with 369mm chainstays. A suspension-corrected rigid CrMo fork is designed to handle rough-and-rowdy riding, and a simple and stout single-speed drivetrain and Tektro mechanical disc brakes ensure a fun and safe ride.
