The 1999 Diamond Back Mr Lucky BMX features a full chromoly Franko-design frame with double-thick dropouts and reinforced bottom bracket and head tube, paired with a matching full chromoly fork using a threadless steerer, 1-1/4” blades, and reinforced dropouts. It comes fitted with 4-piece chromoly handlebars offering an 8” rise in chrome, held by a forged alloy A-head stem (1-1/8”). Braking is handled by a Dia-Compe 990 U-brake with Dia-Compe MX-99 lever, while the drivetrain uses a DB three-piece chromoly 180mm crank in chrome with a chrome alloy 44-tooth chainwheel, matched to alloy platform pedals. The wheelset consists of Alex alloy double-wall 20x1.75” 48-hole rims, high-flange alloy hubs with 14mm rear axle, and 14-gauge stainless spokes, wrapped in Comp III-style 20x2.125” tyres front and rear. Comfort comes via a DB super-padded seat with 8mm rails and chromoly seatpost.
