The 1998 Diamond Back Mr Lucky BMX features a full chromoly frame with oversized tubes, double-thick dropouts, a reinforced bottom bracket and head tube, plus box chain stays for added strength. Up front is a full chromoly fork with a 4mm crown insert, double-thick dropouts, and 1-1/4” blades. It runs 4-piece chromoly handlebars with an 8.5” rise, finished in chrome, paired with a forged alloy A-head stem (1-1/8”). Braking is handled by a Dia-Compe 990 U-brake with MX-101 lever, while drivetrain duties fall to a DB one-piece chromoly 180mm crank in chrome, matched to DB alloy platform pedals with chromoly 1/2” axles. Rolling stock includes Alex alloy double-wall 20x1.75” 48-hole rims, alloy high-flange hubs, and 14G stainless spokes, wrapped in Comp III-style tyres (20x1.75” rear, 20x2.125” front). Comfort comes via a DB padded seat with 8mm rails and a chromoly micro-adjust seatpost (25.4mm). The bike is finished in black with chrome detailing.
